Question

27.  Use a labelled potential energy diagram to show how the addition of a catalyst would impact the activation energy of an endothermic reaction.

Answer 1

Addition of catalyst does not change the enthalpy of reaction but it reduces activation energy of forward reaction and backward reaction by same amount, which cause increase in the rate of the reaction,

Therefore, addition of catalyst increase rate of reaction by lowering activation energy shown below.
