Vedclass · Answer

(A) Activation energy $(E_a)$ is defined as the minimum amount of extra energy required by a reactant molecule to get converted into the product. In a chemical reaction, the reactants must reach a high-energy state known as the transition state (or activated complex) before they can form products. The activation energy is calculated as the difference between the energy of the transition state and the average energy of the reactants. Mathematically, $E_a = 	ext{Energy of transition state} - 	ext{Energy of reactants}$.
