Fe:56,O:16,Si:28,Ca:40,C:12,Al:27g/mol 2. A pig iron containing 0.1%S,0.3%Si,3.4%C,0.8%Mn, and 1.8%P is desulfurized at 1300C according to the following two reactions: 1. [S]iwts+(CaO)(s)+[C]=(CaS)(s)+CO(g),G1e=23,09025.14Tcal 2. [S]iws+2(CaO)(s)+1/2[Si]=(CaS)(s)+1/2(2CaO.SiO2)(s). G2=53,945+17.85Tcal Assuming that iron is saturated with carbon and all solid compounds are pure and pco=1atm, show that desulfurization is favored in the presence of silicon, given that, fs=3.6 and fsit=4.5
