Assertion (A): For every chemical reaction at equilibrium, standard Gibbs enegry of the reaction is zero.
Reason (R ) : At constant temperature and pressure chemical reactions are spontaneous in the direction of the decreasing Gibbs energy.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is True. Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Staement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
D
At equilibrium `DeltaG` (Gibbs energy)`=0 "but" DeltaG^(@)` (standard Gibbs energy)`cancel=0`
As `DeltaG` (Gibbs energy) is more negative reaction will be more spontaneous.
