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.
When a process releases energy into the surroundings it's called exothermic (from the Greek thermo meaning heat, and exo meaning outside). The most obvious effect of an exothermic chemical reaction is a rise in the temperature of the reaction mixture.
