Solution:
∆H and ∆S are negative
The given response addresses the development of chlorine particle from chlorine molecules.
Here, bond development is occurring. Along these lines, energy is being delivered. Thus, ∆H is negative.
Likewise, two moles of iotas have more haphazardness than one mole of a particle. Since immediacy is diminished, ∆S is negative for the given response.
