Edexcel IAL Chemistry A2 13.8 Total entropy and equilibrium constants
Preserve natural logarithms and compatible units, infer K above or below one from the entropy sign and track temperature through ΔSsurroundings when required.
How this is tested
- Apply ΔStotal = R ln K and relate the sign of total entropy to whether K exceeds one.
- Calculate K or total entropy with natural logarithms, R and consistent units.
- Explain temperature effects on total entropy and therefore on equilibrium-constant magnitude.
