Question

Consider the reaction A + B ? products

From the following data obtained at a certain temperature, determine the rate law, the order of the reaction, and calculate the rate constant k.

Experiment 1: [A] = 1.50 M; [B] = 1.50 M; Initial Rate = 3.20 x 10-1 M/s

Experiment 2: [A] = 1.50 M; [B] = 2.50 M; Initial Rate = 3.20 x 10-1 M/s

Experiment 3: [A] = 3.00 M; [B] = 1.50 M; Initial Rate = 6.40 x 10-1 M/s

order of reaction = 1

k = 0.213 s-1

Rate = k[A][B]

order of reaction = 2

k = 0.142 s-1

Rate = k[A]2

order of reaction = 2

k = 0.142 s-1

Rate = k[B]

order of reaction = 1

k = 0.213 s-1

A. Rate = k[A]

order of reaction = 1

k = 0.213 s-1

B.

Rate = k[A][B]

order of reaction = 2

k = 0.142 s-1

C.

Rate = k[A]2

order of reaction = 2

k = 0.142 s-1

D.

Rate = k[B]

order of reaction = 1

k = 0.213 s-1

Explanation / Answer

Rate = k[A][B]

order of reaction = 2

k = 0.142 s-1

B.

Rate = k[A][B]

order of reaction = 2

k = 0.142 s-1
