Draw a reaction profile (diagram of energy vs reaction coordinate) for a hypothetical reaction AB +C <=> A+BC in which the foward reaction has an activation energy of 100kJ mol-1 and the backward reaction has an activation energy of 75kJ mol-1. (ii). a catalyst introduces an extra step into the reaction and reduces Ea for the 1st step to 50kJ mol-1. Indicate the effect of the catalyst on the diagram. (iii). how would you expect the equilibrium constant for this reaction to vary with temperature?
