Question

Consider the following statements: The law for the acid-catalysed hydrolysis of an ester being given as rate = K[H+][ester] = K'[ester]. If the acid (strong) concentration is doubled at constant ester concentration,
1. The second-order rate constant, K, is doubled.
2. The pseudo first-order rate constant, K', is doubled.
3. The rate of reaction is doubled.
Which of the above statement is correct?

Prashant Kotian · Accepted Answer

Correct answer: B. K is independent of concentration. K' = K[H+] is doubled; rate = K'[ester] is doubled. Thus statements 2 and 3 are correct.
