Endo - during reaction heat is absorbed
for eg - heating of washing soda to intiliaze the process

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
