Chemistry Question on Order of Reaction

The order of a reaction for an esterification process is

A

zero

B

first

C

second order

D

pseudo first order

Answer

second order

Explanation

Solution

R−C∣∣O−OHcarboxylic acid+HO−R′alcohol→H+R−C∣∣O−OR′ester+H2O\underset{carboxylic \, acid }{R-\overset {||^O}C -OH} + \underset {alcohol}{HO - R'} \xrightarrow {H^+} \underset {ester}{R - \overset {||^O}C - OR'} + H_2 O
Rate of reaction= k [carboxylic acid] [alcohol]
So, order of reaction = 2
