Question

how is exothermic reaction different from endothermic reaction?

Answer 1

Answer:

In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system. A popular example of an endothermic chemical reaction is photosynthesis.

Answer 2

$\ddag \; \underline{\bf{Exothermic \; Reaction}} \; \ddag$

➣ Release of heat.

➣ Surrounding temperature increases.

➣ Example : Burning of coal.

$\ddag \; \underline{\bf{Endothermic \; Reaction}} \; \ddag$

➣ Absorption of heat.

➣ Surrounding temperature decreases.

➣ Example : Photosynthesis.
