Solution: Sulfonation of benzene has the following mechanism:(1) 2H2SO4 ⟶ H3O+ + HSO4- + SO3                                      [fast](2) SO3 + C6H6 ⟶ H(C6H5+)SO3-                                            

Problem

Sulfonation of benzene has the following mechanism:

(1) 2H2SO4 ⟶ H3O+ + HSO4- + SO3                                      [fast]
(2) SO3 + C6H6 ⟶ H(C6H5+)SO3-                                                        [slow]
(3) H(C6H5+)SO3- + HSO4- ⟶ C6H5SO3- + H2SO4                [fast]
(4) C6H5SO3- + H3O+ ⟶  C6H5SO3H + H2O                         [fast]

(a) Write an overall equation for the reaction.
