Detailed explanation-1: -All chemical reactions need energy to get started. Even reactions that release energy need a boost of energy in order to begin. The energy needed to start a chemical reaction is called activation energy.
Detailed explanation-2: -Activation energy is the minimum energy required to cause a reaction to occur. To understand activation energy, we must first think about how a chemical reaction occurs. Anyone who has ever lit a fire will have an intuitive understanding of the process, even if they have not connected it to chemistry.
Detailed explanation-3: -The activation energy for the forward reaction is the amount of free energy that must be added to go from the energy level of the reactants to the energy level of the transition state.
