Vaporization of Water

Postby MCracchiolo 1C » Sun Feb 11, 2018 9:53 pm

Why is the Gibbs Free Energy at 100 (degrees C) for the vaporization of water, zero?

Hi! I think the Gibbs free energy is zero because the system is at equilibrium. The rate of reaction for liquid water turning into a gas is the same as the rate of reaction for gas turning into a liquid.
