Question -
Answer -
ΔH and ΔS arenegative
The given reaction represents the formationof chlorine molecule from chlorine atoms. Here, bond formation is taking place.Therefore, energy is being released. Hence, ΔH is negative.
Also,two moles of atoms have more randomness than one mole of a molecule. Sincespontaneity is decreased, ΔS is negative for the given reaction.
