Webl) The Gibbs free energy of a system is increasing in any spontaneous process going on at constant T and P. decrease m) The expansion of a gas into a vacuum is an example of an increase in entropy. n) Enthalpy change and entropy change are two properties of a reacting system that determine whether a process at constant pressure and temperature ... WebSo it's 0.242 kilojoules per Kelvin. And so now our Gibbs free energy right here is going to be minus 890 kilojoules minus 290-- so the minus and the minus, you get a plus. And that makes sense, that the entropy term is going to make our Gibbs free energy more positive.
