The energies of activation for forward and reverse reactions for A2 + B2 
2AB are 180 kJ mol–1 and 200 kJ mol–1 respectively. The presence of a 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) – [AIEEE 2007]

Most Upvoted Answer
The energies of activation for forward and reverse reactions for A2 + ...
The correct answer is Option D.
In presence of catalyst,
E(forward) = 80kJ/mol and,
E(reverse) = 100kJ/mol.
Therefore, H(reaction) =E(reverse)−E(forward)
=100−80
=20kJ/mol.
In presence of catalyst,
E(forward) = 80kJ/mol and,
E(reverse) = 100kJ/mol.
Therefore, H(reaction) =E(reverse)−E(forward)
=100−80
=20kJ/mol.
