Explanation:
A catalyst HAS precisely NO EFFECT on the thermodynamics of a reaction......this is chemistry not magic. They can provide an alternative reaction pathway that can alter the energy of activation for a reaction positively or negatively......
This is best appreciated by reference to graphs..
)
The enthalpy change of the catalyzed versus uncatalyzed reaction is PRECISELY the same. The activation energy of the catalyzed reaction is much lower, which means that a greater proportion of reactant molecules have the requisite activation energy, and the reaction proceeds faster.
