The change in Gibbs freee energy for vaporisation of a pure substance is

Answer & Solution
Correct Answer: Option C
Since, the gibbs free energy for vaporization of a pure substance is $$dG=VdP-SdT$$    since during phase change the temperature and pressure remains constant the gibbs free energy remains constant.
