Question

What are the signs of delta h and delta s for the reaction 2cl gives cl2?

Answer 1

∆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.

Answer 2

HEYA MATE HERE U GO.

⭐. Delta H : Negative .Because energy is released in bond formation.

⭐. Delta S ; Negative. Because entrophy decreased when atoms combine to form molecules.
