Q:

You are given the following reaction:
A + 2B → C

Three experiments were done to determine the rate law for this reaction. The following results were obtained:
Trial 1: [A] = 0.1, [B] = 0.05, Initial Rate = 1 x 10^-4
Trial 2: [A] = 0.1, [B] = 0.1, Initial Rate = 2 x 10^-4
Trial 3: [A] = 0.2, [B] = 0.1, Initial Rate = 5 x 10^-5

What is the rate law for this reaction?

A

Rate = [A][B]

B

Rate = [A]²[B]

C

Rate = [A][B]²

D

Rate = [A]^-2[B]
