727℃ Kc 3.8×10^(-5) I2(g) ⇌ 2I(g) Kc Kp

727℃ Kc 3.8×10^(-5) I2(g) ⇌ 2I(g) Kc Kp

 

 

The equilibrium constant Kc for the reaction

I2(g) ⇌ 2I(g)

is 3.8×10^(-5) at 727℃.

Calculate Kc and Kp for the equilibrium

2I(g) ⇌ I2(g)

 

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

 

Kc = 1 / (3.8×10^(-5)) = 2.6×10^4

( 참고: 이론적 평형상수 https://ywpop.tistory.com/4154 )

 

 

 

Kp = Kc (RT)^Δn

( 참고 https://ywpop.tistory.com/6523 )

 

= (2.6×10^4) (0.08206 × (273.15+727))^(-1)

= 3.2×10^2

 

 

Δn = 1 – 2 = –1
