Be sure to answer all parts. phosgene (cocl2) is a toxic substance that forms readily from carbon monoxide and chlorine at elevated temperatures: co(g) + cl2(g) ⇌ cocl2(g) if 0.530 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)? substance concentration (m) co cl2 cocl2
