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 correct answer is the choice “c"; activation energy. For all chemical reactions, a minimum amount of energy is required to form the activated complex from the reactants. This is necessary for a reaction to occur. This amount of energy is called, activation energy.
Detailed explanation-3: -Hence, the minimum value for the activation energy will be equal to △H.
Detailed explanation-4: -Activation energy, by definition, is the minimum amount of energy required for reactants to form products.
Detailed explanation-5: -In chemistry and physics, activation energy is the minimum amount of energy that must be provided for compounds to result in a chemical reaction. The activation energy (Ea) of a reaction is measured in joules per mole (J/mol), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
