- Gibbs free energy is a measure of enthalpy taking entropy into account.
- It allows us to relate the two factors at a given temperature to find if the reaction is spontaneous.
- If Gibbs is negative, the reaction will occur and if positive it will not happen ().
- The change in Gibbs free energy is related to the emf of a redox reaction by the equation .
