What is the relation between kp and kc?

The relationship between Kp and Kc is Kp = Kc (RT)^Δn

Derivation of Relation between Kp and Kc

For a general reaction aA + bB ⇌ cC + dD

K_c is an equilibrium constant denoted in terms of molar concentrations.

K_c= \({[C]^c[D]^d \over [A]^a[B]^b}\)

K_p is an equilibrium constant denoted in terms of partial pressures.

K_p = \((PC)^c(PD)^d \over (PA)^a(PB)^b\)

P = \(nRt \over V\)= [Conc]RT

Kp = \({([C]RT)^c([D]RT)^d \over ([A]RT)^a([B]RT)^b} = Kc {(RT)^c(RT)^d \over (RT)^a(RT)^b}\)

Therefore, the relation between Kp and Kc is expressed as –

K_p = K_cRT^Δn
