Finding Rate Law from Concentration vs Time Data

In this lesson, Mike discusses and strategizes how we should solve the worst kinetic problem scenario:
The one where they give is a bunch of numbers of concentration reactant vs. time and they NEVER tell us the reaction order!
Mike has a a strategy. We shall survive.

DUUUUUDE!!!!! Those first 30 seconds were my exact thoughts!!!!!! :O

thank you so much sir, i was stuck on my assignments for hours, now i got it

And if we had an addition reaction, could we determine the odder and rates in the same way?

[@generalchemistrywithmike]

Sure! If provided with the concentrations vs. time, it shouldn't matter which type of reaction it is. Sounds like you are currently suffering through organic 1 or 2? Most addition reactions should be bimolecular, or second-order overall, first order with respect to each reactant (i.e. nucleophile and electrophile).

Thank you, Mike! The Aleks platform and other TH-cam videos were far from helpful. It makes more sense to find the k values for two points with each integrated equation since these are constants. As well as list the y values for each order equation and look at the difference between two points to observe a constant change! My program had me calculating all of the integrated y-values and then trying to plot those by hand, and only afterward finding the k values by taking delta concentration change over delta time. I really thought this was the topic my mind was going to break and I would finally declare insanity! :)

Thank you for your comment! I tell my students at this very point it's basically the peak of the activation energy of general chemistry, part 2.

You have really helped me
Thank you very much ☺️😭❤️🥂

I have a trouble, what should i do, if i get non linear for 1st and 2nd orde? In firts trial i get 26% eror at first orde and get more than 26% eror at 2nd orde. Could i define that the orde is 1st orde ? Hopefully you see and help me to find a way 😢
