If it's a single step well, and the width of the well is fairly constant, then the steeper the slope is (stronger bonds are like stiffer springs) the deeper the well will be. You can extract the most energy with the deepest well. It seems like gravity potential energy mental model works moderately well for chemical potentials (or more accurate enthalpy) at relatively low temperatures (vs bond energy) for statistically large numbers of molecules.
