The Recovery Time Objective (RTO) is the duration of time and a service level within which a business process must be restored after a disaster in order to avoid unacceptable consequences associated with a break in continuity.
Exothermic Reaction Examples. Exothermic chemical reactions release heat to the environment. Photo Credit: AITCH, Getty Images. An exothermic reaction is a chemical reaction that releases heat and has a negative enthalpy (-Î´H) and positive entropy (+Î´S).. These reactions are energetically favorable and often occur spontaneously, but sometimes you need a little extra energy to get them started.

An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants â products + energy.
