Problem

Propanal (A) is converted to product P in the presence of catalyst C by the two-step mechanism shown. (1) C+A→k1CA\text{C} + \text{A} \xrightarrow{k_1} \text{CA} (fast) (2) CA+B→k2C+P\text{CA} + \text{B} \xrightarrow{k_2} \text{C} + \text{P} (slow) Assuming the concentration of the intermediate CA remains effectively constant during the reaction, which of the following rate laws is predicted for the formation of P? a) rate =k[A][B]=k[\text{A}][\text{B}] b) rate =k[A][C]=k[\text{A}][\text{C}] c) rate =k[A]=k[\text{A}] d) rate =k[A][B][C]=k[\text{A}][\text{B}][\text{C}]
