Kc와 Kp. CO(g) + 2H2(g) ⇌ CH3OH(g) has Kp=6.3×10^(-3) at 225°C

Kc와 Kp. CO(g) + 2H2(g) ⇌ CH3OH(g) has Kp=6.3×10^(-3) at 225°C

 

 

The reaction CO(g) + 2H2(g) ⇌ CH3OH(g) has Kp = 6.3×10^(-3) at 225 °C. What is the value of Kc for this reaction at this temperature?

 

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

 

▶ Kp = Kc • (RT)^Δn

▶ Kc = Kp / (RT)^Δn

▶ Δn = 기체 생성물들의 몰수 - 기체 반응물들의 몰수

( 참고 https://ywpop.tistory.com/6523 )

 

 

Δn = 1 - (1+2) = -2

 

Kc = Kp / (RT)^Δn

= (6.3×10^(-3)) / [(0.08206) (273.15+225)]^(-2)

= 10.53

 

 

답: Kc = 11
