From the following data comment on the feasibility of production of titanium (i) by carbothermic reduction of TiO2 at 1200C and (ii) via chlorination of TiO2 at 1200C under reducing conditions and subsequent reduction of TiCl4 with magnesium at 750C. Given that: Ti(s)+O2(g)=TiO2(s),Gi=223,500+415ST,cal2C(s)+O2(j)=2CO(e),G2=53,4004190T,calTi(s)+2Cl2(g)=TiCl4(g),G3=180,70018TlogT+3465T,calMg(i)+Cl2(g)=MgCl2(0),G4=147,8501358TlogT+7277T,cal
