- 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.
