Calculate the change in molar Gibbs energy of carbon dioxide (treated as a perfect gas) at 20 oc when its pressure is changed isothermally from 1.0 bar to (a) 3.0 bar. (b) 2.7 x 10-4 atm. its partial pressure in dry air at sea level.

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
