When the concentrations of reactants and products in gaseous reactions are expressed in terms of their partial pressure, then the equilibrium constant is represented as Kp.
∴ For the reaction,
A(g) + B(g) ⇌ C(g) + D(g)
The equilibrium constant (Kc) can be expressed using partial pressure as :
Kp = \(\frac{P_C \times P_D}{P_A \times P_B}\)
Where PA, PB, PC and PD are equilibrium partial pressures of A, B, C and D respectively.
