Mark the incorrent statements.

Options

A. Catalyst provides an alternative pathway to reaction mechanism
B. Catalyst raise the activation energy
C. Catalyst lowers the activation energy
D. Catalyst alters enthalpy change of the reaction

Answer

B, D

Explanation

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.
