Question

What is exothermic and endothermic reaction in dsc?

Answer 1

Exothermic- the reaction which evolve heat during the reaction is called the exothermic reaction

Endothermic-the reaction which absorbs the heat during reaction is called endothermic

Exothermic example-A+B--C+D+E

ENDOTHERMIC- A+ B +E---C+D

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
