The energies of activation for forward and reverse reaction for A2 + B2 \(\text { ⇌ }\) 2AB are 180 kJ mol–1 and 200 kJ mol–1 respectively. The presence of catalyst lowers the activation energy of both (forward and reverse) reactions by
100 kJ mol–1. The enthalpy change of the reaction
(A2 + B2 → 2AB) in the presence of catalyst will be
(in kJ mol–1).
