Answer:

energy of activation is the correct answer.

Explanation:

  • All the chemical reactions including an exothermic reaction require activation energy to initiate a reaction.
  • Activation energy is the minimum amount of energy required to activate the molecules to the situation that they can experience a chemical change.
  • If the activation energy is lower the faster the reaction occurs.
  • Joules, kilocalories/mol, kilojoules per mole are the units for activation energy.
