Pure Phosgene gas (COCl2), 0.0300 mol, was placed in a 1.60 L container. It was heated to 890 K as well as at equilibrium the pressure of CO was found to be 0.517 atm. Compute the equilibrium constant Kp for the reaction
CO(g) + Cl2 (g) ----------- COCl2 (g)
Is the efficiency of a carnot engine affected by the heat capacity of the gas. i.e if the heat capacity varies with temperature.
