Question

Differentiate between endothermic and exothermic reaction 10 class​

Answer 1

The difference between endothermic and exothermic reactions lies in the words themselves. "Thermic" refers to heat, just as in the word "thermometer." "Exo" means "outside" and "endo" means "inside." Thus, an endothermic reaction pulls heat into an object or area, while an exothermic reaction expels heat. From this basic definition of the terms, you can understand a variety of other facts about these two types of chemical reaction.

Answer 2

AnsWer :

$\large\orange{\star\underline\mathfrak{Exothermic \: reaction:-} }$

• Those reactions in which heat is released are known as Exothermic reactions.

• Example :- When carbon burns in oxygen to form,carbondioxide a lot of heat is produced.The reaction as follows:

$\normalsize\sf\ C + O_2 \longrightarrow\ CO_2 + heat$

• To indicate, releasing heat we show "heat energy", "heat" or simply "Energy", in products.

$\large\orange{\star\underline\mathfrak{Endothermic \: reaction:-} }$

• Those reactions in which heat is absorbed, are known as Endothermic reactions.

• Example :- When Nitrogen and Oxygen are heated to a high temperature (of about 3000°C) they combined to form nitrogen oxide and a lot of heat is absorbed in this reaction.The reaction as follows :

$\normalsize\sf\ N + O_2 + heat \longrightarrow\ NO_2$

• To indicate the absorbing heat,we indicate "heat" in reactants.
