Definition

These are chemical reactions that do not occur spontaneously because they require an input of energy to proceed. They have a positive change in Gibbs free energy.

Gibbs Free Energy:

The maximum amount of work a system can perform at constant temperature and pressure without any outside intervention.

Activation Energy:

The minimum amount of energy required for a chemical reaction to occur, similar to the initial push needed to start rolling the ball uphill.
