4. An energy diagram for electrophilic aromatic substitution of benzene with Br2 with FeBr3 as catalyst below. The rate-limiting step is formation of the sigma complex (Step 1). Generally, any factor that stabilizes the sigma complex also stabilizes the transition-state leading to that complex. This effect leads to a lower transition-state energy and a faster reaction. rate-limiting transition state reactants + Br + FeBrz Η Br FeBr + O energy intermediate products Br + HBr + FeBr 3 -45 kJ/mol...
