Hydrochloric acid (HCl) dissociate on positive ions or cations of hydogen (H⁺) and negative ions or anions of chlorine (Cl⁻). When there is free cations and ions, water solution can conduct electricity. Chloroform do not dissociate on ions in water, because that is not polar molecule, so chloroform is in molecular form in solution.
Answer:

Explanation:
Hello!
In this case, since the Gibbs free energy of any process is related with the enthalpy change, temperature and entropy change as shown below:

For a chemical reaction it is simply modified to:

Thus, since the enthalpy of reaction is given as -304.2 kJ and the entropy as -414.2 J/K (-0.4142 kJ/K), at 775 K the Gibbs free energy of reaction turns out:

Whose result means this is a nonspontaneous reaction.
Best regards!
They both have the same atomic number
