An experiment was performed for the decomposition of phosgene gas to form carbon dioxide and chlorine at 527 degrees celsius. The equilibrium constant for the reaction at 527 degrees celsius, is 4.63 × 10^-3. initially, only phosgene was present in the reaction vessel. At equilibrium, the concentration of phosgene at 527 degrees celsius was 0.0864molL-1. calculate the equilibrium concentration of carbon monoxide
