Question

To derive a relation between K_p and K_c for the reaction :

H₂(g) + CO₂(g) H₂O(g) + CO(g)

Answer 1

H₂(g)+C0₂(g)$\to$ H₂0(g)+C0(g)

Kp=kc(RT)^Δn

Kp= (P_H2O) (P_C0)/(P_H2)(P_CO2)

Kc=[H₂0][CO]/[H₂][CO₂]

PV=nRT

P=(n/V)RT

n/V=Concentration,[].

$\therefore$ P=[]RT

Kp=[H₂0]RT[CO]RT/[H₂]RT[CO₂]RT

Kp=[H₂0][CO]/[H₂][CO₂]

$\therefore$ Kp=Kc
