Detailed explanation-1: -Activation energy is defined as the minimum amount of extra energy required by a reacting molecule to get converted into product. It can also be described as the minimum amount of energy needed to activate or energize molecules or atoms so that they can undergo a chemical reaction or transformation.

Detailed explanation-2: -The energy needed to start a chemical reaction is called activation energy. Activation energy is like the push a child needs to start going down a playground slide.

Detailed explanation-3: -All chemical reactions, including exothermic reactions, need activation energy to get started. Activation energy is needed so reactants can move together, overcome forces of repulsion, and start breaking bonds.

Detailed explanation-4: -All reactions require an initial input of energy to proceed, called the activation energy.

Detailed explanation-5: -The role of activation energy in a chemical reaction is to start the reaction by arranging the reactants appropriately and breaking their existing bonds. Activation energy is the energy needed to start a reaction and is required in all chemical reactions.
