JEE Main 2007 Chemistry question
The energies of activation for forward and reverse reactions for are 180 kJ and 200 kJ respectively. The presence of catalyst lowers the activation energy of both (forward and reverse) reactions by 100 kJ . The enthalpy change of the reaction in the presence of catalyst will be (in kJ )
Answer: (4)
Solution
kJ/mol; a catalyst lowers both activation energies equally (80
