The G difference between the axial and equatorial conformations of methylcyclohexane (7.4 kJ mol 1 , 1.74

The ΔG° difference between the axial and equatorial conformations of methylcyclohexane (7.4 kJ mol^–1, 1.74 kcal mol^–1; see Fig. 7.9) is about the same as the ΔH° difference. Calculate the percentages of axial and equatorial conformations present in one mole of methylcyclohexane at 25 °C.
