Does Energetically Favorable Mean?

All Answers (7) The "energetically more favorable" reaction (or molecular interaction) means that the deltaG^o of the process is more negative. The molecular interaction thermodynamics strongly depends on local environment and positions of reactants relatively each other before and after the reaction.

Does energetically favorable mean spontaneous?

Closed 4 years ago. I read somewhere that the difference between energetically favorable reactions and spontaneous reactions is that energetically favorable reactions are ones where energy is released, i.e., ΔH<0, whereas spontaneous reactions are ones where the change in Gibbs free energy is negative, i.e., ΔG<0.

What does it mean to be energetically unfavorable?

An Unfavorable Chemical Reaction Can Proceed If It Is Coupled with an Energetically Favorable Reaction. Many chemical reactions in cells are energetically unfavorable (ΔG > 0) and will not proceed spontaneously. One example is the synthesis of small peptides (e.g., glycylalanine) or proteins from amino acids.
