Chapter 14, Problem 105P(choose chapter or problem)
In 1899 the German chemist Ludwig Mond developed a process for purifying nickel by converting it to the volatile nickel tetracarbonyl \(\left[\mathrm{Ni}(\mathrm{CO})_4\right]\) (b.p. \(=42.2^{\circ} \mathrm{C}\) )
\(\mathrm{Ni}(\mathrm{s})+4 \mathrm{CO}(\mathrm{g}) \leftrightharpoons \mathrm{Ni}(\mathrm{CO})_4(\mathrm{~g})\)
(a) Describe how you can separate nickel and its solid impurities.
(b) How would you recover nickel? \(\Delta \mathrm{H}_f^{\circ}\) for \(\mathrm{Ni}(\mathrm{CO})_4\) is - \(602.9 \mathrm{~kJ} / \mathrm{mol}\).]
