Difference between exothermic reaction and endothermic reaction |
|
Answer» The removl of energy and heat in any chemical reaction is known as exothermic reaction. The addition of energy and heat in any chemical reaction is known as endothermic reaction. In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. While, the exothermic reaction releases energy into the surrounding from the system. Exothermic reactions:\tIf "chemical reactions" release energy into their surroundings, it is called as exothermic reactions.\tIn this reaction, the temperature increases during the progress of the reaction.\tReactants enthalpy is higher than the products.\tEnthalpy change is negative.Endothermic reactions:\tIf the chemical reactions absorb the heat energy from their surroundings, it is called exothermic reactions.\tIn this reaction, the temperature will decrease during the progress of reactions.\tReactants enthalpy is lower than the products.\tEnthalpy change is positive." |
