ΔG=0

Postby Ashley Garcia 2L » Fri Feb 09, 2018 9:38 pm

What does it mean when ΔG=0? Why does ΔG=0 at the boiling point of a substance?

When delta G equals 0, the system is in equilibrium. Delta G also equals zero at phase changes.

When delta G is zero, that means the system is at equilibrium and has no available energy. At boiling point it is zero because there is no change in temperature or pressure, therefore, by delta G = (delta H of vaporization) - (T of vaporization) X (delta S of vaporization) =0. It is also zero at the freezing point.
