The Kroll process is used to manufacture titanium metal from titanium(IV) chloride:
TiCl4(g)+2Mg(l)→Ti(s)+2MgCl2(l) \text{TiCl}_4\text{(g)} + 2\text{Mg(l)} \rightarrow \text{Ti(s)} + 2\text{MgCl}_2\text{(l)} TiCl4(g)+2Mg(l)→Ti(s)+2MgCl2(l)Explain how the atom economy of this industrial process can be improved.
