- AEndothermic reaction
- BExothermic reaction
- CEither exothermic or endothermic
- DNeither exothermic nor endothermic
✓
Answer
- Exothermic reaction
Explanation:
Cl⋅ + Cl⋅ → Cl : Cl
As two Chlorine atoms come together their electrostatic energy decreases. According to the law of conservation of energy, this energy will be transformed into heat energy.
So, Cl + Cl → Cl2 is exothermic reaction.
