Kc Kp 관계식. CH3OH(g) ⇌ CO(g) + 2H2(g) [CH3OH] 0.20 M 400℃

For the reaction: CH3OH(g) ⇌ CO(g) + 2H2(g),

with the equilibrium concentrations for

[CH3OH] = 0.20 M, [CO] = 0.44 M, and [H2] = 2.7 M,

determine the gas phase equilibrium constant (Kp) at 400℃.

------------------------

CH3OH(g) ⇌ CO(g) + 2H2(g)

Kc = [CO] [H2]^2 / [CH3OH]

( 참고 https://ywpop.tistory.com/7136 )

= ((0.44) (2.7)^2) / (0.20)

= 16.038

CH3OH(g) ⇌ CO(g) + 2H2(g)

Δn = 기체 생성물들의 몰수 – 기체 반응물들의 몰수

= 3 – 1 = 2

Kp = Kc • (RT)^Δn

( 참고 https://ywpop.tistory.com/6523 )

= (16.038) (0.08206 × (273.15 + 400))^2

= 48937

답: 4.9×10^4
