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.
The activation energy diagram is drawn as a hill because there is a large amount of energy needed to form the unstable transition state (viewed as the upward slope on the diagram). The difference between this peak energy and the rectants' energy is the activation energy.
