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.
If heat is given off, the reaction is exothermic. Exothermic means that during the reaction, molecules have moved from a higher state of energy to a lower state. An endothermic reaction is the opposite. This is when a reaction starts colder and ends up hotter, taking in energy from start to finish. In an endothermic reaction, the system gains heat as the surroundings cool down. In an exothermic reaction, the system loses heat as the surroundings heat up.
