Gibbs free energy change, ΔG
What this topic asks you to be able to do
- give the Gibbs equation ΔG⦵ = ΔH⦵ – TΔS⦵ and apply it
- work out values by carrying out calculations with the equation ΔG⦵ = ΔH⦵ – TΔS⦵
- state, from the sign of ΔG, whether a process or reaction is feasible
- predict how a change in temperature bears on whether a reaction is feasible, with the standard enthalpy and entropy changes provided
