At а temperаture оf 25°C, the stаndard Gibbs free energy оf fоrmation (ΔGf∘​) is -630 kJ/mol for SiCl4(g) and -580 kJ/mol for MgCl2(s). Compute the standard Gibbs free energy change (ΔG∘) for the reaction: SiCl4(g) + 2 Mg(s) → 2 MgCl2(s) + Si(s), and assess the spontaneity of this reaction at 25°C when the pressure of SiCl4(g) is maintained at 1 atm.
