1. A reaction in which A, B, and C react to form products is first order in A, second order in B, and zero order in C. Which of the following most accurately represents the rate law for this reaction?a. Rate = k [B]2b. Rate = k [A]1 + [B]2 + [C]0c. Rate = k [A]3d. Rate = k[A]1[B]2
2. The following reaction is second order in [A] and the rate constant is 0.025 M-1s-1: A ? B The concentration of A was 0.65 M at 33 s. The initial concentration of A was __________ M.
