Question

State the differences between endothermic exothermic reaction

Answer 1

1. In endothermic reaction energy is supplied to the compound for reaction to take place whereas in exothermic reaction heat is given out during reaction.
2.all decomposition reaction are endothermic where as almost many a combination reaction are exothermic.

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
