Consider the nitration of benzene using ...

Consider the nitration of benzene using mixed conc. `H_(2)SO_(4)` and `HNO_(3)`. If a large amount of `KHSO_(4)` is added to the mixture, the rate of nitration will be `:`

A

Faster

B

Slower

C

Unchanged

D

Doubled

Text Solution

Verified by Experts

The correct Answer is:
B
Slower, as larger amount of `HSO_(4)^(-)` will decrease ionisation of `H_(2)SO_(4)` that result in lesser ionisation of nitric acid and lesser formation of nitronium ion `[NO_(2)^(+)] `
