2.0 L 0.30 atm SO2, 0.16 atm Cl2, 0.50 atm SO2Cl2 K = 0.011

2.0 L 0.30 atm SO2, 0.16 atm Cl2, 0.50 atm SO2Cl2 K = 0.011

 

 

A gaseous reaction mixture contains

0.30 atm SO2, 0.16 atm Cl2, and 0.50 atm SO2Cl2 in a 2.0 L container.

K = 0.011 for the equilibrium system

SO2Cl2(g) ⇌ SO2(g) + Cl2(g)

a) Is the system at equilibrium? Explain.

b) If it is not at equilibrium,

in which direction will the system move to reach equilibrium?

SO2Cl2(g) ⇌ SO2(g) + Cl2(g)

평형상수, K = (P_SO2) (P_Cl2) / (P_SO2Cl2)

 

 

 

반응비, Q = (0.30) (0.16) / (0.50) = 0.096

 

 

 

Q > K 이므로,

a) 평형 상태가 아니다.

b) 역반응 방향. (반응물 쪽 방향)
