The rate law of nitration of benzene using a mixture of nitric acid and sulphuric acid is

Options

A. rate `=k ["benzene"] [NO_(2)^(+)] [H^(+)]`
B. rate `= k [HNO_(3)] [H_(2)SO_(4)]`
C. rate `= k ["benzene"] [NO_(2)^(+)]`
D. rate `= k ["benzene"] [H_(2)SO_(4)]`

Answer

C

Explanation

Nitration of benzene is a second order reaction (first order with respect to benzene and first order with respect to `NO_(2)^(+)` ) ltbr. `:.` Rate = `k` [Benzene] `[NO_(2)^(+)]`
