Question

What do you understand by exothermic and endothermic reaction ? Write its chemical reaction

Answer 1

Heya !!!

Here's your answer !!!

Endothermic Reaction :

The chemical reaction in which the energy is absorbed is called Endothermic reaction ...

Reactants ➡Products + Q
+Q represents that energy is absorbed...

Exothermic reaction :

The chemical reaction in which the energy is released during the reaction is called Exothermic reaction ...

Reactants ➡ Products -Q

-Q represents that energy is released...


Hope this helps you :)

Answer 2

Hello Dost ☺

Answer :

Exothermic reaction and endothermic reaction:

On the basis of energy changes during chemical reaction, they can be classified as

i) Exothermic reaction: A chemical reaction in which heat energy is produced.

Eg : C + O2 → CO2 (g) + heat

ii) Endothermic reaction: A chemical reaction in which heat energy is absorbed.

Eg : CaCO3 + Heat → CaO + CO2
