2. Consider a closed vessel containing a mixture of ideal gases A and B that undergo the chemical reaction: A=bB, where b is an unknown stoichiometric coefficient. The equilibrium mole fraction xд is measured but xB is unknown. The equilibrium mole fraction xд increases when the temperature in the vessel is increased with the pressure held constant and Ꮖ Ꭺ decreases when the pressure in vessel is increased with the temperature held constant. Explain these observations in terms of inequalities involving the enthalpy of reaction AH and the stoichiometric coefficient b in Eq. (7).
