What is the most endothermic reaction?

Answer 1

The most exothermic reaction is nuclear fusion, which is the power of a hydrogen bomb. Nuclear fission is also extremely exothermic.
An extremely exothermic chemical (as opposed to nuclear) reaction, although maybe not the most ever, is the so-called thermite reaction. Fe2O3 + 2Al ---> Al2O3 + 2Fe ΔH = -851.5 kJ/mol See the Related Questions and Web Links to the left of this answer for more information.

Answer 2

This question isn't very meaningful. The temperature of some chemicals which are reacting depends on what temperature they were at before / the background temperature, heat conductivity of the surroundings, as well as the rate of the reaction. The rate itself depends on the concentrations of the reactants (and catalyst, if any) and the temperature.

Answer 3

A reaction is said to be exothermic if it releases energy in the form of light or heat. Exothermic reactions comes under chemical changes since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.

Answer 4

An exothermic reaction release heat; burning is a typical example of exothermic reaction.

Answer 5

The chemical reactions which proceed with the release of energy are called Exothermic reaction.

Example: 2Mg + O2 -------- 2MgO
