Question

Compare and contrast exothermic and endothermic reactions with specific example.

Answer 1

The reaction in which heat is liberated out is known as exothermic reaction.eg the mixing of water in any acid is highly exothermic

The reaction in which heat is absorbed is known as endothermic reaction. E.g respiration

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
