What is the difference between an exothermic reaction and an endothermic reaction?

Solution

Exothermic reaction
Endothermic reaction
A chemical reaction in which heat energy is evolved is called an exothermic reaction.
Chemical reaction in which heat is absorbed are called endothermic reaction.
The evolution of heat leads to a rise in the temperature of the solution.
The absorption of heat leads to a fall in the temperature of the solution.
Example: $C (s) + O_{2} (g) \to {CO}_{2} (g) + heat Carbon Oxygen Carbon dioxide$
Example: $6 {CO}_{2} (g) + 6 H_{2} O (l) + heat \to C_{6} H_{12} O_{6} (s) + 6 O_{2} (g) Carbon dioxide Water Glucose Oxygen$
