A sealed container filled with 0.6 moles of H2(g), 1.4 moles of ethene C2H4(g), and 0.01 moles of ethane (C2H6(g)) at 300K. The initial total pressure in the container is 4.7 bar. Calculate the amounts of each component in the mixture at equilibrium for the reaction H2(g) + C2H4(g) ⇌ C2H6(g). You may not assume that the entropies and enthalpies are temperature independent (but you can assume Cp's are temperature independent). You may treat the gases ideally. Also, please calculate ΔG for going to equilibrium.
Once the system reached equilibrium in (A), assume you expand the volume by a factor of 300. Calculate the new composition of molecules in your container and ΔG to go from the equilibrium state in (A) to a new equilibrium state.
