Question

In the pseudo-first-order acid-catalyzed hydrolysis of an ester, reaction progress is monitored by titrating reaction aliquots against $NaOH$. If $V_0$, $V_t$, and $V_\infty$ are the base volumes required at times zero, $t$, and infinity, the correct analytical rate constant expression is:

Prashant Kotian · Accepted Answer

Correct answer: C. The total initial concentration of ester () is strictly proportional to the total acid generated, . The unreacted ester remaining at time , , is proportional to the acid yet to be generated, . Thus, .
