• question_answer1) The energies of activation for forward and reverse reactions for \[\frac{1}{4}\] are \[\frac{1}{2}\]and\[5\,\Omega \]respectively. The presence of a catalyst lowers the activation energy of both (forward and reverse) reactions by\[(1-e)\] The enthalpy change of the reaction \[({{A}_{2}}-{{B}_{2}}\,\to 2\,\,AB)\] in the presence of catalyst will be (in\[(1-{{e}^{-1}})\])       AIEEE  Solved  Paper-2007
