# Help Me Watch

1. In the reaction A + B → Products, the order w.r.t. A is 2 and the order w.r.t. B is zero. Using the value of the rate constant (0.008), calculate the rate of reaction if [A] = 0.04 mol dm-3 and [B] = 0.04 mol dm-3

Ive been given this question and am struggling to work it out. Can anyone guide me through the process of working it out please.

So since B is zero order you know that it doesnt take part in the rate determining step. However this is a theory calculating concept this is how it goes.
Rate=k(A)^m(B)^n
Rate= 0,008x0.04^2x0.04^0
Rate=1.28x10^-5

Well i've deleted it now since I dunno what I did to offend a bunch of people! If people explained rather than being nasty then it would be resolved quicker and help the OP more!

you didnt offend no and no one was being nasty

he was simply saying that if you give him the answer straight away it doesnt help his undertsadning
