Activation Energy

Subject: Chemistry

Book: General Chemistry

Activation energy (Ea) is the minimum energy required for a reaction to proceed. It represents the energy barrier between reactants and products. According to the Arrhenius equation, increasing temperature or introducing a catalyst lowers the effective energy threshold, accelerating the reaction. Visualizing Ea on an energy diagram helps understand how certain reactions can be slow at low temperatures but rapid when heated.
