At 1273 K, the Delta_(f)G^(@) of MgO(s) and CO(g) and -941 and -"439 kJ.mol"^(-1). But at 2273 K, the Delta_(f)G^(@) of MgO(s) and CO(g) are -314 and -"628kJ.mol"^(-1) . On the basis of the given values of Delta_(f)G^(@) , predict the temperature at which carbon is used as a reducing agent for MgO(s).
