Q. $CH_{3}COOC_{2}H_{5} + H_{2}O\overset{\ \ \ \ \ \ H + \ \ \ \ \ \ }{\rightarrow}CH_{3}COOH + C_{2}H_{5}OH$ is an example of …… order.
A) Zero
B) Second
C) Third
D) Pseudo first order
Explanation
(d)
$CH_{3}COOC_{2}H_{5} + H_{2}O\overset{H +}{\rightarrow}CH_{3}COOH + C_{2}H_{5}OH$
Since, in this reaction, water is excess, it is an example of psedo first order reaction (as rate depends only on the concentration of $CH_{3}COOC_{2}H_{5}$).
