What are these partial pressures?

Question

Kc = .00463
T = 800 K
for the reaction:

COCl(sub. 2)(g) <=> CO(g) + Cl(sub. 2)(g)

Calculate the equilibrium partial pressure of all the components, starting with pure COCl(sub. 2) at 0.760 atm.

Answer 1

Solve x squared/(0.76 - x) = 0.00463 for the pp of both CO and Cl2.

And then you can work out the phosgene as well.
