    This goes hand in hand with the fact that when enthalpy is endothermic (delta H is greater than 0), then when it has a lot of temp it’s spontaneous (goes to the right) and when it lowers temp, it goes to the left is non spontaneous.

    In any reaction where it is reversible and we have reactant and products and equilibrium is reached, if there is ever a stress factor involved like increase/ decrease temperature, increase/ decrease pressure there is going to be a new equilibrium will be established. Increasing yield by concentration when we want more product we raise the concentration of the reactants to shift reaction towards the right and vice versa.

    Mr Anderson, does adding or removing solids and liquids from a reaction (which involves them) actually affect the concentrations and thus the equilibrium?
    One of my textbooks says that it 'does not shift the equilibrium' because you 'cannot change the concentration of a pure liquid or solid as they are 100% pure'.
    Another book says that it does affect the equilibrium position, which is quite different to what the first book says.

    • @anilmishra744
      @anilmishra744 9 ปีที่แล้ว

      it does not affects the equilibrium as the solids and pure liquids donot change with time. they remain constant during the course of a chemical reaction.

    • @tejasshyam
      @tejasshyam 8 ปีที่แล้ว +2

      +Tejas Chandrasekar : If in a classroom of 40 students, 10 students are asleep (and are hence 'unresponsive' or 'unreactive' to the teacher), will their removal from class make a difference to how the class is being conducted? Not much! Similarly when molecules of a solid, where the atoms cannot react much because they are bonded very tightly to each other, are removed from the reaction, it makes no significant difference. A similar argument can be made for addition of solids as well.
      Perhaps this blog chemistrified.wordpress.com will help you in visualizing the Le Chatelier's principle a little better. Hope it helps!

    Great vid sir!
    Just a little comment. If you're taking a test and it doesn't give you the energy flow (positive or negative) then what Mr Anderson was using there is called enthalpy. So basically, for the reversible process of turning hydrogen and nitrogen gas into ammonia, on the forward reactants side, there are 4 mol of gas while on the forward products side, there are only two, so during the process heat was released.
    Also, catalyst doesn't shift the equilibrium. With a one way reaction, it helps making the reaction go to completion faster. But, in a two way reaction, it makes the reaction reach equilibrium more quickly.

    Guys, please help me out:
    Let's say the Reactants have less moles than the Products. When we decrease the pressure, why do the Reactants with FEWER MOLES move towards the Products with MORE MOLES? i don't understand... what makes the system shift to the right??

    • @aleksko1574
      @aleksko1574 8 ปีที่แล้ว +3

      Yes, because remember, when you INCREASE the pressure - the equilibrium shifts to the side with fewer molecules of gas, basically because it can expand, produce more molecules to hit the walls of the container. If you decrease the pressure the equilibrium will move in such a way that the pressure increases again. It can do that by producing more molecules. In this case, the position of equilibrium will move towards the right-hand side of the reaction.

    Hey Great video however, with the reaction of N2O4 to 2NO2 when you increase pressure or decrease volume why would the reaction shift right first and then go to the side of fewer moles? I thought that it would shift left to reactants first and stay there till the volume would allow the product of nitrogen dioxide to form? A little confused

    After we place a stress on the reaction (by removing/adding reactants) and allowing that reaction to come to a new equilibrium, does the new equilibrium still have the same equilibrium constant? Afterall, it is referring to the same chemical equation.

    • @HanTran-yi4sb
      @HanTran-yi4sb 4 ปีที่แล้ว +1

      Yes, since for a given reaction, at a temperature, Kc stays the same. The only thing that changes is Q. When the equilibrium is thrown off, the value of Q will change (in other words, Q no longer equals to Kc). According to Le Chatelier's principle, the reaction will shift in the direction that restore the equation: Q = Kc.

    • @tejasshyam
      @tejasshyam 8 ปีที่แล้ว

      +metalguitar311 : let's try to think of it with a physical analogy. If we're in a room full of boys and girls looking to get married by meeting up with each other and we add more boys to the room, there is greater chance that those girls who weren't finding a match earlier may now find a better suited match and hence land up marrying. Thus, the number of couples increases, but the number of girls left single decreases. In the example you've stated, treat NH3 like the couples (increases), H2 like the boys (added more) and N2 like the girls (number of molecules left behind without reaction decreases). You may also perhaps understand a little better by reading up about this on my blog chemistrified.wordpress.com/2016/04/02/le-chateliers-principle/ where i've tried to explain in a little more detail. Hope this helps!

    how is there more heat on the right side (ammonia) if its exothermic ? exothermic reactions lose heat, making the ammonia colder, and endothermic reactions would make the products warmer, so why would it shift to the left if theres more heat already on the reactants?
    Im sorry, i know you're right, im just confused

    • @HanTran-yi4sb
      @HanTran-yi4sb 4 ปีที่แล้ว

      I think you swapped the concepts of exothermic and endothermic reactions. Exothermic reaction means that the reactants are higher in energy (if you look at the energy diagram), products are lower in energy, and heat is released along with the products (meaning heat is a 'product', delta H < 0, and the surrounding gains heat). If the exothermic reaction happens in a beaker, when you wrap your hand around the beaker after some time, you will feel your hand gets warmer, not colder. On the other hand, endothermic reaction means that reactants are lower in energy, products are higher in energy, and you must input energy (by increasing temperature, etc.) for the reaction to happen. In this case, heat is a 'reactant', delta H > 0, and the surrounding loses heat (as the endothermic reaction "steals" the input/surrounding heat to supply its own reaction), and you will feel the beaker gets colder. I hope this clears things up!

    • @HanTran-yi4sb
      @HanTran-yi4sb 4 ปีที่แล้ว

      Not sure if you still need an answer, but I'll give it a try. Usually, if the question asks how increasing/decreasing temperature affects the equilibrium of a reaction, you will also be given the energy diagram or delta H or some qualitative measure to figure out if the reaction is endo- or exothermic. An example of qualitative measure (word description) is the beaker gets hotter or colder after a while. If exothermic, delta H < 0, the beaker will get warmer (since heat is releasing to the surrounding), reactants are higher in energy than products (meaning in the energy diagram, if energy increases on the positive y-axis, the position of reactants will be higher than that of products). If endothermic, delta H > 0, beaker will get colder (since heat or energy is absorbed from the surrounding to supply the reaction), reactants are lower in energy than products (the position of reactants will be lower than that of the products).
