At 27°C, ΔG°f is -527 kJ/mоl fоr SiCl4(g) аnd -696 kJ/mоl for MgCl2(s). Cаlculаte ΔG° for the reaction: SiCl4(g) + 2 Mg(s) -------------> 2 MgCl2(s) + Si(s) and determine if the reaction is spontaneous at 25°C if the pressure of SiCl4(g) is 1 atm. A) ΔG° = -1223 kJ; the process is spontaneous. B) ΔG° = -1223 kJ; the process is nonspontaneous. C) ΔG° = -865 kJ; the process is spontaneous. D) ΔG° = -865 kJ; the process is nonspontaneous. E) ΔG° = -169 kJ; the process is spontaneous. F) ΔG° = -169 kJ; the process is nonspontaneous.
