How we find a reaction is exothermic or endothermic?
Most Upvoted Answer
How we find a reaction is exothermic or endothermic?
Reaction involved with releasing of heat energy along with the product is called "Exothermic Reaction".
Examples:
1. Burning of Coal.
C + O2 = CO2 + Heat↑.
2. Combustion of natural gas.
CH4 + 2O2 = CO2 + 2H2O + Heat↑.
3. Respiration.
C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy↑.
As you can see the above reactions, where heat is liberated. Hence it is called "Exothermic Reaction".
Reaction involved with absorption of heat energy is called "Endothermic Reaction".
Examples:
1) Mixing water with Potassium Chloride.
2) Mixing water and Ammonium nitrate.
3) Reacting Ethanoic acid with Sodium Carbonate.

How we find a reaction is exothermic or endothermic?
If heat is produced as product in reaction then its exothermic reaction and if the heat is listed as reactant in reaction then it is endothermic.
