The change in the molar volume accompanying fusion of solid benzene is 0.5 cm3 mol−1. Determine the change in Gibbs energy of fusion when the pressure is increased from 1 bar to 5000 bar.
3) An ideal gas consisting of one mole of molecules of type A is in contact with the
surroundings at T=300 K, and under a constant pressure of 1 atm. The gas undergoes a
spontaneous isomeric chemical reaction, wherein some fraction x of molecules of type A
change shape, become isomers of type B. This results in an equilibrium mixture of 1-x moles
of A and x moles of B. The enthalpy of B is lower than the enthalpy of A by 3 kJ/mole, such
that AH = -xɛ; & = 3kJ/mole . The change in entropy is given by
AS ==R(xln x+ (1–x)ln(1– x)).
Use the computer to graph the change in Gibbs free energy as a function of x. Determine, by
inspection of your graph, or otherwise, the concentration of A and the concentration of B
when equilibrium is obtained. What is the maximum work that could be extracted from this
process (aside from PV work)?
