Question

6. For the reaction 2cl(g) cl2(g) what will be the sign of h and s ?

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 reaction.

Answer 2

HEYA MATE HERE U GO.

⭐. Delta H : negative because energy is released in bond formation.

⭐. delta S : negative because entropy decreases when atoms combine to form molecules
