Entropy, Enthalpy, and Gibbs Free Energy Practice Problems

WebGibbs free energy (∆G) is the relationship between the change in enthalpy (∆H) and the change in entropy (∆S) to determine the feasibility of a reaction. We say it is the amount of energy in a system available to do work. We express this relationship in the equation: ∆ G Θ = ∆ H Θ - T ∆ S Θ. Where ∆G is the change in free energy. http://scientifictutor.org/1686/chem-college-calculate-delta-g-first-way/
