Question

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

Options

A.(dS)V,E > 0, (dG)T,P < 0
B.(dS)V,E = 0, (dG)T.P = 0
C.(dS)V,E = 0, (dG)T,P > 0
D.(dS)V,E < 0, (dG)T,P < 0

Solution

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