The energies of activation forward and revers reaction for `A_(2)+B_(2)to2AB` are 180 kJ `mol^(-1)` and 200 kJ `mol^(-1)` respectively. The pressure of a catalyst lowers the activation energy of both (forwar and reverse) reactions by `100 kJ mol^(-1)`. The magnitude of enthalpy change of the reaction `(A_(2)+B_(2)to2AB)` in the presence of catalyst will be (in Kj `mol^(-1)`):A. 280B. 20C. 300D. `-20`
