Answer»

Catalyst PROVIDES an alternative pathway to REACTION mechanism
Catalyst raise theactivationenergy
Catalyst lowersthe activation ENERGY
Catalyst alters enthalpy CHANGE of thereaction

Solution :Function of Catalyst As the catalyst is added to the reaction medium rate of reation increases by decreasing activation energy of molecule. Hence, it follows an alternative pathway.
Catalyst does not change the enthalpy change of reaction. Energy of reactant and product remain same in both catalysed and UNCATALYSED reaction.
Hence, (a) and (d) are incorrect statements.
