∆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.
