Answer #1

here sulfuric acid will donate H+ to nitric in first step, since the Pka value (-3) of sulfuric acid shows it has lower pH than nitric acid, therefore more acidic compare to nitric acid and nitric acid will act as base to form nitronium ion, this nitronium ion will undergo electrophilic substitution reaction with benzene
