WebDec 8, 2024 · A reaction coordinate diagram is a graph that plots energy versus reaction progress. The amount of energy that needs to be added is called the activation energy , which is the point where the line ... 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 endergonic reactions. In this case, the … Now based on that logic what do you think this word means, endothermic. Well … It's going to be spontaneous. Now, let's think a little bit about why that makes …
