Hi,

Attached here, is one of the questions that I don't get.

I understand on how they were able to get that the order for [A] was 1 but, but I would really like to know if there is a math savvy way of solving for the reaction order of B?

They suggest doing a "multiples table" but how often do you use this on the MCAT? And is it really practical on test day?

Thanks in advance!

Can you post the solution as well?....That's a tricky one....It looks like a first order reaction to me with respect to A... I don't see how AAMC would do something like that...They usually give reasonable numbers that people can work with.

The solution is in the green box Temperature10🙂 The answer is C.

You want me to post how they got to it?

Yes... Sorry...I was thinking that solution is different from answer.
