Edexcel IAL Chemistry A2 16.11 Ecell, entropy and equilibrium constant
Use the sign and proportional relationships carefully: positive E°cell links to positive ΔS total and lnK, but E°cell is not directly proportional to K itself.
How this is tested
- Link positive E°cell with positive total entropy change and positive lnK.
- Use given relationships and constants to calculate ΔS total or an equilibrium constant.
- Choose the correct proportional graph between E°cell and total entropy change.
