Problem

A covalent bond has a standard Gibbs free energy of 400 kJ/mol, while the hydrogen bond and van der Waals forces have substantially lower values, respectively 25 and 5 kJ/mol. Given such ∆G° values, which of the following is equivalent to the ratio of the Keq value of a covalent bond to that of a hydrogen bond? (RT = 2500 J/mol)
