JEE MAIN - Chemistry (2003 - No. 3)

In an irreversible process taking place at constant T and P and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria :
(dS)V, E > 0, (dG)T, P < 0
(dS)V, E = 0, (dG)T, P = 0
(dS)V, E = 0, (dG)T, P > 0
(dS)V, E < 0, (dG)T, P < 0

Explanation

For spontaneous reaction, $$dS > 0$$ and $$dG$$ should be negative i.e. $$ < 0.$$
