Question

Different between axothermic and endotharmic reactions
​

Answer 1

Exothermic reaction

• Chemical reaction in which energy is evolved (given out) is known as exothermic reaction.

Example

1. CaO + H20 → Ca(OH)2 + heat
2. SO2 + O2 → 2SO3 + heat
3. Zn + H2SO4 → ZnSO4 + H2 + heat

Endothermic reaction

• Chemical reaction in which energy is absorbed is known as endothermic reaction.

Example

1. C + 2S → CS2 - heat
2. N2 + O2 → 2NO - heat
3. H2 + I → 2HI - heat

Answer 2

Answer:

exothermic reactions release heat during reactions while endothermic reactions absorbs heat during reaction.
