The given reaction represents the formation of a chlorine molecule from its atom. Bond formation taking place, therefore the energy is released during this. So, \Delta H is negative.

 Two moles of an atom have more randomness than the one mole of chlorine. So, spontaneity is decreased. Hence \Delta S is negative.
