18.93 The standard free energies of formation (AG) of the three isomers of pentane (see p. 365) in the gas phase are: n-pentane: -8.37 kJ/mol; 2-methylbutane: -14.8 kJ/mol; 2,2-dimethylpropane: – 15.2 kJ/mol. (a) Determine the mole percent of these molecules in an equilibrium mixture at 25°C. (b) How does the stability of these molecules depend on the extent of branching?
