Hi, can anyone help me with this question?

Thank you very much!!!

Hi!

rate=k * [A]^m * [B]^n

to find n we look at the trials that keeps A constant

r2/r3 = (k * [A2]^m * [B2]^n) / (k * [A3]^m * [B3]^n)

1/1 = (k * 0,3^M * 0,1^n) */ (k * 0,3^m * 0,3^n)

1 = (1/3)^n

0 = n

to find m we look at the trials that keep B constrant

r1/r2 = (k * [A1]^m * [B1]^n) / (k * [A2]^m * [B2]^n)

1/9 = (1/3)^m

-2 = m (not sure why i don’t find +2???)

So rate = k [NO2]²[CO]⁰ = k[NO2]²

Is C) the correct answer?

Yup it’s C, I got it, thank you so muchhh!!!

Have a great day!!!

Hi Juliette! I’m doing IB past papers chemistry and have some questions, if you don’t mind, can I direct message to you to ask it?

Thank you so much!!!

Yes of course! Although i don’t know how to solve a lot of IB questions i’d love to try
