Question

What is Endothermic Reaction ?​

Answer 1

Answer:

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Answer 2

$\huge\bf{Answer :}$

A reaction in which the heat is absorbed by different reactants from the surrounding in order to form products is known as Endothermic reaction.

$\huge\bf{Extra\: Information :}$

1) These type of reactions causes cooling effect.

• Reason - After absorbing heat, these reactions drastically reduces the atmosphere's temperature and hence, produces a cooling effect.

2) These type of reactions causes the formation of different bonds by the process of absorbing heat from the atmosphere.

3) Here, the enthalpy change ( depicted by ∆H ) is considered as postive.

4) Example of some endothermic reaction :-

• NH4Cl (s) + H2O (l) ⟶ NH4Cl (aq) – Heat
