How to solve gibbs free energy 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. Webaddresses Gibbs Free Energy, equilibrium constants, and electrolysis calculations. Each chapter contains sample problems and practice problems to help further understanding of how math and chemistry go hand in hand. The Answer Key is an excellent resource for any undergraduate course that deals with the basic concepts of general chemistry.
