Total 2 Average 5 5 What Is The Heat Of Combustion What Is The Definition Of Enthalpy Of Combustio Heat Energy Chemical Reactions Exothermic Reaction What is the term used to describe the energy needed to get a reactions started. . The free energy of the reactants and products do not change just the threshold energy level needed for the reaction to commence. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products. The activation energy is the energy required to start a reaction. A cohesion energy b chemical energy c activation energy d adhesion energy. In other words the reaction requires energy to proceed. The rate of reaction increases if the activation energ...
