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 on Edexcel A Level Chemistry Gibbs free energy. Each one builds up to exam-style questions. 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.
