The analysis of the inner reaction-diffusion layer yields the heat flux produced by the exothermic reaction. I n (3.7b) expressing the kinetic law governing the heat flux released by the exothermic reaction, we have only retained the flame temperature modification (#, $; 1). This is because these eight reactions are exothermic whereas the others are endothermic. The reason for the low barrier is that the reaction is quite exothermic at 20 kcal molx1. Fusion reactions are studied worldwide on a large scale since about 1942 for exothermic reactions. To be feasible this transfer must be close to thermoneutral (or exothermic), since the actual methane formation cannot start out at a too high energy. After this, the resulting hydroxyl radical is immediately quenched in a strongly exothermic step. This local maximum exists because the pressure behind the shock decreases as a result of the exothermic reaction and/or geometric expansion. The reactions have no entrance barriers and are all exothermic. Neuronal responses are typically slow in cold conditions with consequences for the survival of exothermic organisms. In the case of propagating reaction fronts the exothermic chemical reaction plays the role of heating from below. If we consider for example an upward propagating exothermic chemical reaction, then the temperature of the medium below the reaction zone is greater than the temperature above it. Clearly, for both primed and control seeds, reactions were still occurring and resulting in an overall exothermic heat flow after seeds had lost the ability to germinate. All reactions were found to proceed without an entrance barrier, to have exit barriers well below the energy of the reactant molecules and to be strongly exothermic. The cause was found to be the result of an organometallic blue pigment which caused an exothermic catalytic reaction with another additive in the foam.

Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Curing of epoxy resins is an exothermic reaction and in some cases produces sufficient heat to cause thermal degradation if not controlled.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Temperature is sometimes increased in a step-wise fashion to control the rate of curing and prevent excessive heat build-up from the exothermic reaction.

This exothermic reaction produces the four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane.

Conversely, it can be seen on the exothermic reaction plot that as temperature increases, the equilibrium constant decreases.
