Insurable interest is one of the foundations of insurance because, in its absence, insurance would be no different from gambling and (even if legal) would not constitute a binding agreement.
Activation energy is the minimum energy that reactant particles  must possess in order for the chemical reaction to occur.    That is defined as the energy that must bâ¦e overcome in order for a  chemical reaction to occur.
Exergonic reactions have a net release of energy, but they still require a small amount of energy input before they can proceed with their energy-releasing steps. This small amount of energy input necessary for all chemical reactions to occur is called the activation energy (or free energy of activation) and is abbreviated E A. Activation energy: Activation energy is the energy required for a reaction to proceed; it is lower if the reaction is catalyzed.
