Question

DEFINE EXOTHERMIC AND ENDOTHERMIC REACTION. GIVE ONE EXAMPLE OF EACH WITH CHEMICAL EQUATION. ​

Answer 1

Answer:

The reaction in which heat or light is evolved is called exothermic

ex- 2h2+o2 gives rise to 2h2o

the reaction in which heat or light is absorbed is called endothermic

N2+o2 give rise to 2NO

Answer 2

Answer:

Exothermic reaction= reaction in which heat is released along with the formation of products are called exothermic chemical reactions.

example -burning of natural gas

Ch4+2o2--->CO2+2H2o

Endothermic reaction= reactions in which energy is absorbed are known as endothermic reactions.

example- 2AgBr------>2Ag+Br2
