Why Gibbs free energy matters

Why Gibbs free energy matters

Exothermic reactions are not automatically the only feasible ones, and endothermic reactions are not automatically impossible. Gibbs free energy brings together enthalpy and entropy so you can predict thermodynamic feasibility at constant temperature and pressure. The key relationship is:

Step-by-step lessons covering Edexcel A Level Chemistry Gibbs free energy for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
