Answer & Solution
Correct Answer
(B) \(\mathrm{A}=\mathrm{R} \quad \mathrm{B}=\mathrm{P} \quad \mathrm{C}=\mathrm{S} \quad \mathrm{D}=\mathrm{Q}\)
Step-by-step Solution
Detailed explanation
For complex reactions, the overall rate of the reaction is determined by the slowest step, which is known as the rate determining step. Thus, A matches with R. For a zero order reaction, the rate is equal to the rate constant \(k\). The unit of rate is…
