Question

For A2 + B2 2AB Ea for forward and backward reaction are 180 and 200 kJ mol–1 respectively If catalyst lowers Ea for both reaction by loo kJ mol–1. Which of the following statement is correct? (A) The enthalpy change for the catalysed reaction is different from that of uncatalysed reaction. (B) The enthalpy change for the reaction is +20 kJ mol–1. (C) Catalyst can cause non-spontaneous reactions to occur. (D) Catalyst does not alter the Gibbs energy change of a reaction.
