The Total solution for NCERT class 6-12
Is it true that under certainconditions, Mg can reduce SiO2 andSi can reduce MgO? What are those conditions?
The temperature at which ΔfG curvesof these two substances intersect is 1966 K. Thus, at temperatures less than1966 K, Mg can reduce SiO2 andabove 1966 K, Si can reduce MgO.
