Edexcel IAL Chemistry A2 13.2 Kp expressions
Edexcel IAL Chemistry A2 13.2 Kp expressions
Use p(species), not concentration brackets, raise every gaseous partial pressure to its coefficient and omit solids and liquids from the expression.
How this is tested
- Write Kp from gaseous partial pressures raised to stoichiometric powers.
- Omit solid and liquid species while retaining every gas in a heterogeneous Kp expression.
- Derive Kp units from the net power of atm after simplifying numerator and denominator.
