Question

write the endothermic and exothermic reaction with example​

Answer 1

Answer:

Endothermic Reaction

The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat. A few examples of the endothermic process are photosynthesis, evaporating liquids, melting ice, dry ice, alkanes cracking, thermal decomposition, ammonium chloride in water and much more.

Exothermic Reactions

The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. A few examples are neutralization, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulfuric acid into water and much more.

Answer 2

Answer:

Exothermic reactions

Exothermic reactions are those reactions in which heat is released.

Reactants → products + heat

For example, formation of ammonia from nitrogen and hydrogen is an exothermic reaction.

N2 (g) + 3H2 (g) → 2NH3 (g) + 92.2kJ

Endothermic Reactions

Endothermic reactions are those reactions in which heat is absorbed.

Reactants + heat → products

For example, dissociation of ammonia into nitrogen and hydrogen is an endothermic reaction.

2NH3 (g) + 92.2kJ → N2(g) +3H2 (g)
