Academics

Phosgene (COCl2) is a toxic substance that forms readily from carbon monoxide and chlorine at elevated temperatures: CO (g)+ Cl2 (g) ? COCl2 (g). If 0.450 mol of each reactant is placed in a 0.500 L flask at 600 K, what are the concentrations of all three substances at equilibrium (Kc = 4.95 at this temperature)?
