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 :

Multiple Choice 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

Step-by-Step Verified Solution

For spontaneous reaction, dS &gt; 0 and dGdG should be negative i.e. &lt; 0.
