WebGibbs free energy. As we have seen in the previous sections, the feasibility of a reaction is determined by two factors, the enthalpy change and the entropy change; The two factors come together in a fundamental thermodynamic concept called the Gibbs free energy (G) The Gibbs equation is: ΔG ꝋ = ΔH reaction ꝋ - TΔS system ꝋ WebGibbs free energy is the amount of energy available in a system to do work.

ΔG depends on temperature and, therefore, so does the equilibrium constant. Graphs of ΔG against temperature show how reaction feasibility changes. As a rule of thumb, if ΔG is more negative than –60 kJ mol-1, the reaction is considered to be complete, and if more positive than +60 kJ mol-1, it is considered … See more We can use ΔStotalto predict the direction of a reaction, but largely for historical reasons chemists prefer to think in terms of energy. The total entropy change is the sum of the entropy … See more We can see from the expression for the Gibbs free energy that the value of ΔGdepends on temperature: ΔG = ΔH – TΔSsystem Sometimes, changing the temperature can … See more Real reactions are more complex.
