Question

An irreversible reaction, A + B → products, is studied under conditions where [B] >> [A]. When [B] = 0.10 M, a plot of 1/[A] vs. time is linear. When [B] = 0.30 M, the plot of 1/[A] vs. time is indistinguishable from the first plot within experimental error. What is the rate law for this reaction?

A.

Rate = k[A][B]

B.

Rate = k[A]^2

✓ Correct
C.

Rate = k[A]^2[B]

D.

Rate = k[A][B]^2
