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 [Activation energy: The minimum energy required for a collision between particles, in order for a reaction to occur.] (E a) for the forward reaction is shown by (A): E a (forward) = H (activated complex) - H (reactants) = 200 - 150 = 50 kJ mol-1. The activation energy (E a) for the reverse reaction is shown by (B): E a (reverse) = H (activated complex) - H (products) = 200 - 50 = 150 kJ mol-1. The enthalpy change for the forward reaction is shown by (C):
