- Temperature
- Pressure of a container
- Volume of a container
- Concentration
- Determine whether enthalpy and entropy favour reactants or products
- Write a Keq expression and perform equilibrium calculations with or without an ICE table
- Determine whether product or reactants are favoured by interpreting Keq
