Dangerous exothermic reactions

WebAn exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, the change in enthalpy ( ΔH) will be negative. WebAutocatalytic reactions have a tendency to begin very slowly, and then suddenly increase in rate due to the formation of catalytic compounds or intermediates. This can be extremely dangerous at large scale, since it …
