- #69Consider the nitration of benzene using mixed conc.
``H_2SO_4`` and ``HNO_3``. If a large amount of ``KHSO_4`` is
added to the mixture, the rate of nitration will be:-
(1) faster
(2) slower
(3) unchanged
(4) doubleddigAnsr: 2Ans : (2)
Sol. Slower, as large amount of HSO4
- will decrease
ionisation of H2SO4 that result in lesser ionisation
of nitric acid and lesser formation of nitronium ion
