A reaction won’t occur unless atoms or molecules of reactants come together. This happens only if the particles are moving, and movement takes energy. Often, reactants have to overcome forces that push them apart. This takes energy as well. Still more energy is needed to start breaking bonds in reactants.

Explanation:
Activation energy is needed so reactants can move together, overcome forces of repulsion, and start breaking bonds
