2CO2(g)+heat⟶2CO(g)+O2(g)

Answer :

Exothermic reactions are

1) 2H2+O2 ⇒2H20+Heat

2) 2C2H2+5O2⇒4CO2+2H20+Heat

Endothermic reactions are

3) CH4+Heat ⇒CO+2H2

4) 2CO2+Heat⇒2CO+O2

What are exothermic and endothermic reactions?

Exothermic reactions are those reactions in which energy is released and in endothermic reactions energy is required to proceed the reaction.

1) & 2) are exothermic because energy is released in reaction 3) & 4) are endothermic because energy is required so called endothermic reaction.
