About Activation Energy
Activation energy (Ea) is the minimum energy required for reactant molecules to undergo a chemical reaction. It represents the energy barrier that must be overcome for the reaction to proceed.
Typical activation energies range from 40-200 kJ/mol for most chemical reactions. Catalysts work by lowering the activation energy.
