At 100 °C the reaction:

Question

SO2Cl2(g) ⇄ SO2(g) + Cl2(g)
has Kp = 2.4.
Calculate the equilibrium composition of the mixture when 1.2 atm of SO2Cl2 are mixed with 0.8 atm of Cl2 at 100 °C.

Answer 1

.......SO2Cl2(g) ⇄ SO2(g) + Cl2(g)
I......1.2..........0........0.8'
C.......-x..........x.........x
E.....1.2-x.........x......0.8+x

Kp = 2.4 = (x)(0.8+x)/(1.2-x)
Solve for x and evaluate each of the components.
