The relationship between Kp and KC is
Kp=KC(RT)Δn ...(i)
Here, Δn= (number of moles of product of gas) - (number of moles of reactant of gas)
Kp= equilibrium constant at constant pressure
Kc= equilibrium constant at constant concentration
R= rate constant
2A(g)⇌B(g)+C(g)
The value of Δn is =2−2=0
Put value of Δn in Eq. (i) we ger,
Kr=Kc(RT)0
⇒[Kp=KC]
