Answer #1

forward reaction activation energy (Ea) = 450 kJ/mol

backward reaction activation energy (Ea') = ?? kJ/mol

heat of reaction = H = -164 kJ/mol

heat of reaction = H = activation energy of froward - activation energy of backward

                       H = Ea - Ea'

                      -164 = 450 - Ea'

                         Ea' = 450+164

                         Ea' = 614 kj/mol

backward reaction (reverse) activation energy (Ea') = 614 kJ/mol
