Question

Mark the incorrect statements.
(a)Catalyst provides an alternative pathway to reaction mechanism
(b)Catalyst raises the activation energy
(c)Catalyst lowers the activation energy
(d)Catalyst alters enthalpy change of the reaction

Answer 1

Answers: (b) and (d) are incorrect statements.

The function of Catalyst As the catalyst is added to the reaction medium rate of reaction increases by decreasing activation energy of the molecule. Hence, it follows an alternative pathway.
Catalyst does not change the enthalpy change of reaction. The energy of reactant and product remain same in both catalysed and uncatalysed reaction.
Hence, (a) and (c) are correct statements.
