A catalyst increase rate of reaction by ...

A catalyst increase rate of reaction by :

A

Decreasing enthalpy

B

Decreasing internal energy

C

Decreased activation energy

D

Increase activation energy

Text Solution

Verified by Experts

The correct Answer is:
C
Catalyst provides new path to the chemical reaction which has lower value of activation energy. Reactant and product with not be affected, so there will not be any change in state parameter like enthalpy and internal energy.

    A catalyst increases the rate of reaction because it:

    Assertion : A catalyst increases the rate of reaction without itself undergoing any permanent chemical change. Reason : A catalyst changes the Gibbs energy (Delta G) of the reaction and equilibrium constant of the reaction.

    (A) Positive catalyst increases the rate of reaction (R) Catalyst decrease the value of DeltaG^(@)

    A : A positive catalyst increases the rate of reaction . R : A positive catalyst alters reaction mechanism and decreases activation energy.

    Assertion (A) : Poistive catalysts increase the rate of reaction. Reason (R ): Catalysts decrease the value of DeltaG^(ɵ) .
