For a phase change H ₂ O (l) (s)

Options

  1. AG=0
  2. BS=0
  3. CH=0
  4. DU=0 .

Correct answer

A. G=0

Step-by-step solution

G^ =-R T K [ G^ = standard free energy change, K= equilibrium constant] If a substance is in equilibrium between two phases at constant temperature and pressure, its chemical potential must have the same value in both the phases. G^ =0 .
