Question

What is the difference between endothermic reaction and exothermic reaction?​

Answer 1

Answer:

Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction. The categorization of a reaction as endo- or exothermic depends on the net heat transfer.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.An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

Answer 2

Answer:

in endothermic reaction

heat is absorbed .

eg.caco3- heat ---cao+CO2

in exotermic reaction

heat is released out.

eg.cu(oh)2- cuo +h20 +heat.
