a gas mixture contains each gas at the indicated partial pressure: 422 mm Hg of CO2, 102 mm Hg of Ar, 165 mm Hg of O2, and 52 mm Hg of H2. What is the total pressure of the mixture in mm Hg?

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
