There is a clear difference between energetically favourable reactions and spontaneous reactions.
Energetically favourable reactions are reactions with Δ H < 0 and spontaneous reactions are reactions with Δ G < 0
You might be more familiar with exothermic ( Δ H < 0) similarly exergonic are reactions with Δ G < 0
Again, I need to prephase that reactions may be exothermic but may not be spontaneous.
For example freezing of ice is exothermic but it cannot happen at 25 C
