Question

Statement -1: For every chmical reaction at equilibrium , standard Gidds energy of reaction is zero
Statement-2: At constant temperature and pressure , chemical reactions are spontaneious in the direction of 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. Statement-1 is False, Statement-2 is True

Answer 1

Correct Answer - D
At equilibrium `DeltaG` (Gibbs energy) =0 but `DeltaG^(@)` (standard Gibbs energy) `ne 0`
As `DeltaG` (Gibbs energy) is more negative reaction will be more spontaneous.
