39. 10 moles of gaseous reactant A dimerize to B in a syringe isothermally. The total Gibbs free energy (G) of the equilibrium state is marked in the right graph. Assuming both A and B behave like an ideal gas, predict the change in G of this system after pressing the piston (the new equilibrium state is marked as #).
