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 `:`

Options

A. doubled
B. faster
C. slower
D. unchanged

Answer

c

Explanation

If large amount of `KHSO_(4)` is added, concentration of `NO_(2)^(+)` will decrease and hence the rate of nitration will be slower.
