Key Concepts

Reaction Energy Diagram

A reaction energy diagram is a graphical representation showing the energy changes that occur during a chemical reaction. It typically plots the potential energy of the system as a function of the reaction coordinate, highlighting key points such as the energy of the reactants, products, and the transition state (the peak of the diagram). This concept helps in visualizing how much energy is required to move from reactants to products.

Endergonic Reactions

Endergonic reactions are processes that require an input of energy because the products are at a higher energy level than the reactants. This is often depicted as an 'uphill' slope on a reaction energy diagram, indicating that energy must be absorbed to overcome the activation barrier and drive the reaction forward.

Exergonic Reactions

Exergonic reactions are those that release energy, meaning the products are at a lower energy level than the reactants. This is visually represented by a 'downhill' slope on a reaction energy diagram, showing that energy is released as the reaction proceeds, often making these reactions spontaneous.
