Edexcel IAL Chemistry A2 13.6 Temperature and equilibrium constants
Treat temperature as the only listed condition that changes K: favouring the endothermic direction increases its relative equilibrium terms and changes the constant accordingly.
How this is tested
- Predict whether K rises or falls after heating from the endothermic reaction direction.
- Infer whether the forward reaction is exothermic or endothermic from the temperature trend in K.
- Use the K expression to connect changed equilibrium partial pressures with the new value.
