Chapter 15, Problem 54E

For the reaction,

  K_c= 255 at 1000 K
$\text{CO}\left(\text{g}\right)+{\text{ Cl}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{COCl}}_{\text{2}}\left(\text{g}\right)$ .

If a reaction mixture initially contains a CO concentration of 0.1500 M and a Cl₂ concentration of 0.175 M at 1000 K, what are the equilibrium concentrations of CO, Cl₂ and COCl₂ at 1000 K?
