Key Concepts

Reaction Coordinate Diagram

A reaction coordinate diagram is a graphical representation that depicts the energy changes during the course of a reaction. It shows the energy level of the reactants, the activation energy barrier at the transition state, and the energy of the products, highlighting that for endothermic reactions, the activation energy is greater than the overall enthalpy change (?H).

Endothermic Reaction

An endothermic reaction is one in which the system absorbs energy from its surroundings, resulting in a positive enthalpy change (?H). The need for additional energy to be absorbed is reflected in the fact that the activation energy must be higher than the net energy change of the reaction.

Activation Energy

Activation energy is the minimum amount of energy required for the reactants to reach the transition state and start the reaction. It represents the energy barrier that must be overcome for the reaction to proceed and is a key factor in determining the reaction rate.

Enthalpy Change (?H)

Enthalpy change (?H) is the heat absorbed or released during a reaction at constant pressure. In the context of an endothermic reaction, ?H is positive, indicating that energy is absorbed from the surroundings as the reactants are converted into products.
