Understanding and using ΔG
Confusion often arises as to exactly what ΔG represents, particularly the difference between ΔGand ΔG⦵. This page covers the three relationships that use ΔG⦵ in the IB and the three main problems encountered by students. ΔG is the change in Gibbs energy for a chemical reaction. If it is measured under standard conditions then it is known as the standard Gibbs energy change and has the symbol ΔG⦵. If the value of ΔG⦵...
