Graph of activation energy
Webactivation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In transition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state … WebExergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called …
