Question

For the reaction,
2 Cl(g) → Cl2,(g), what are the signs of delH and delS ?​

Answer 1

Answer:

∆H and ∆S are negative  

The given reaction represents the formation of chlorine molecule from chlorine atoms.  

Here, bond formation is taking place. Therefore, energy is being released. Hence, ∆H is negative.  

Also, two moles of atoms have more randomness than one mole of a molecule. Since spontaneity is decreased, ∆S is negative for the given reaction.
