You have such an easy, clear, and positive teaching style - thank you for this incredible example of instruction! I'm certain that your students come away from your class feeling confident about their understanding.
Your teaching is so great, specially use your arm to demonstrate the path of the reaction, very easy to pick up and memorize it. Love the way you are showing.
I love how instead of just telling us to remember a certain concept you show us how it works and why it works. It makes remembering it 10x easier. I appreciate this video.
I'm a chemistry major and trying to memorize things is my weakness. I'm a visual learner and this helped me SO MUCH for my quiz tomorrow! Thanks so much!
Hi Kelly, I am so proud of you for searching to make things make sense rather than memorizing. Well done. Happy to hear you are a chemistry major - way to go:)
Thank you so much for the visual demonstration, it makes it so much easier to understand! I had a hard time with this concept in class so I watched a bunch of tutorial videos on it and still didn't get it until I came across your video. You're an awesome teacher!
you are God sent , seriously thank you so much , i was struggling with this concepts until i came across your video. you explained everything perfectly thank you so much!!!🙏🏿💯
wow, finally you explained it like A B C simply using easy terms and relatable examples and found your channel 2 days before the final chem exam, wish me luck
Thank you so very much for this! I’m doing my AS levels this year and I have my mocks coming up in January. I’d always get confused with the direction.. really grateful 😇
Hi Ajeet, I’m so glad it can help especially considering unusual circumstances. I hope your class goes well. Thank you for the love from Nepal. God bless you and your beautiful country.
Thank you so much for this I'm struggling with understanding this concept and i was literally shedding tears cause i couldn't get it, because when colour change get involved it's so confusing, thank you 💗
This was by far the most helpful lecture out there we actually lack teachers like you, do you still teach would love to be a part of any online classes you conduct, have a nice day :)
Hi Destroyer’s Den, I’m so glad it was helpful! I am teaching, but everything is in person right now. In 2020-21 I did teach online synchronously with in person classes. However, for now I only have the videos posted. Let me know if you are looking for a video on a certain topic. Thanks!
@@OldSchoolChemistry can you do some on high school practical papers? That will be great, fo ex.- Representation, averages, trial and error etc used in practical papers.... Thanks a lot
@@busyinverse4300 Hi TJ, that is an EXCELLENT idea. I spend time with my students on those topics. I will see what I can put together for videos. Thanks!

Hi H4mood, Way to go! You are going to do great on your exam. God bless you! I just prayed for you. Many blessings in your future endeavors after you graduate. Well done!
Hi Salmamohammed, When you change the temperature the value of Kc changes. In contrast when you change concentration or pressure/volume, the value of Kc remains the same. You can still predict which way the reaction will shift when temperature is changed, but calculating the new Kc value is beyond the scope of this class. I hope your class goes well!
THANK YOU, but i do have a question, so if the reaction is endothermic and we add heat, the system will decrease the heat and become exothermic (system response) and shifts to the right? and vice versa. If it was exothermic, would it be endothermic (system response) if we added heat and it would shift to the left?
i have a question beside the video when we increase the temperature in endothermic reaction the Kaq increases !! how so ?since the endothermic has the heat in the reactants side and in the Keq equation the reactants is in the denominator so it should decreases ?! i hope that you answer me . thank you very much ma'am
Hi Osamah, When you increase the temperature in an endothermic reaction the reaction shifts forward making more products and consuming reactants. Keq = Products/Reactants, more products means a higher Keq. Remember when you change temperature you actually change the Keq value. When you change pressure or concentration the value of Keq does not change. I hope that helps! Thanks:)
Great question. The surrounding gets cold. Say a salt is dissolved in water and the temperature of the solution decreases. That is an endothermic dissolution. It required more energy to dissociate the ions than the energy released when the water molecules surrounded the ions. Evidence of this fact is the solution temperature decreased. Energy went from the solution into the reaction (endothermic reaction). I hope that helps. Thanks!

What about the Kc. What happens to it when rasing then lowering temperature?
Hi Salmamohammed, When you change the temperature the value of Kc changes. In contrast when you change concentration or pressure/volume, the value of Kc remains the same. You can still predict which way the reaction will shift when temperature is changed, but calculating the new Kc value is beyond the scope of this class. I hope your class goes well!

in endothermic reaction, the system becomes cold or hot?
Great question. The surrounding gets cold. Say a salt is dissolved in water and the temperature of the solution decreases. That is an endothermic dissolution.
