What does one mean by exothermic and endothermic reaction? Give example |
|
Answer» In exothermic reaction heat is released along with products where as ln endothermic reaction heat is absorbed Exothermic Reaction: A chemical reaction in which heat is given out is known as exothermic reaction. For exampleC(g) + O2(g) → CO2(g) + Heat EnergyNaOH(aq) + HCl (aq) → NaCl(aq) + H2O(l) + EnergyEndothermic Reaction: A chemical reaction in which heat energy is absorbed is known as endothermic reaction. For exampleN2(g) + O2(g) → 2 NOC(s) + H2O → CO(g) + H2(g) In exothermic heat is released and in endothermic heat is absorbed |
