General Chemistry — Thermodynamics & Equilibrium
Energy, entropy, Gibbs free energy, and Le Chatelier's principle in biological contexts.
What you need to know
1ΔG = ΔH – TΔS: spontaneity depends on both enthalpy and entropy contribution at that temperature
2Le Chatelier: adding a product shifts equilibrium left — reaction quotient Q vs. K
3Henderson-Hasselbalch: pH = pKa + log([A–]/[HA]) — buffer capacity is maximum at pH = pKa
4Electrochemistry: positive ΔE° means spontaneous, negative means non-spontaneous
