Exothermic reaction and some examples are as follows : An exothermic reaction is a chemical reaction that releases heat and has a negative enthalpy (-ΔH) and a positive entropy (+ ΔS). These reactions are energetically favorable and often happen spontaneously, but sometimes you need a little extra energy. Endothermic reactions. Photosynthesis. Photosynthesis is the chemical reaction that takes place in green plants, which uses energy from the sun to change carbon dioxide and water into food that the plant needs to survive, and which other organisms (such as humans and other animals) can eat so that they too can survive.

Exothermic reaction examples

The reaction between petrol and oxygen which I have mentioned is an example of an exothermic reaction. Because it releases heat or heats up the surrounding. Endothermic Reaction: On the other hand when a reaction cools up the surroundings or decreases the temperature of the surroundings is an endothermic reaction. If the direction of a reversible reaction is changed, the energy change is also reversed. · For example: the thermal decomposition of hydrated copper(II) sulphate is Exothermic processes release energy upon completion, and are signified by a negative change in enthalpy.

A chemical fire is a great exothermic example.
