With the increasing number of factories and the industries, a noticeable amount of methane has been released to the atmosphere so far, and they have the ability to exist in the atmosphere for about 10-12 years. It can also be reduced when undergoes chemical reaction in the atmosphere.

Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
