Consider the reaction:
SO2Cl2(g)⇌SO2(g)+Cl2(g)
Kp=2.91×103 at 298 K
In a reaction at equilibrium, the partial pressure of SO2 is 0.135
atm and that of Cl2 is 0.342 atm .
Part A
What is the partial pressure of SO2Cl2 in this mixture?
Solution :-
Lets make the ICE table
SO2Cl2(g) ⇌ SO2(g) + Cl2(g)
0 0.135 0.342
+x -x -x
X 0.135-x 0.342-x
Kp = [SO2][Cl2]/[SO2Cl2]
2.91*10^3 = [0.135-x][0.342-x]/[x]
2.91*10^3 *x = [0.135-x][0.342-x]
Solving for x we get
X= 1.58*1^-5
Therefore the partial pressure of the SO2Cl2 at equilibrium = 1.58*10^-5 atm
