The equilibrium constant Kp is deduced from the equation for a reversible reaction occurring in the gas phase.
Kp is the equilibrium constant calculated from partial pressures for a system at constant temperature.
Students should be able to:
- derive partial pressure from mole fraction and total pressure
- construct an expression for Kp for a homogeneous system in equilibrium
- perform calculations involving Kp
- predict the qualitative effects of changes in temperature and pressure on the position of equilibrium
- predict the qualitative effects of changes in temperature on the value of Kp
- understand that, whilst a catalyst can affect the rate of attainment of an equilibrium, it does not affect the value of the equilibrium constant.
