1.	A part of Ellingham diagram for some metal oxides (Based upon 1mole of O_2) and carbon is shown. In figure A,B,C and D represent curves for metal oxides and a,b,c,d ,e and f are temperatures. Answer the following : (i) Will B oxide reduce metal oxide of A or C or both ? (ii) Which metal can be reduced thermally ? (iii) Will oxide of B be reduced by coke above temperature c or below temperature c ? (iv) Will the formation of CO or CO_2 be preferred above temperature f ? (v) What does temperature 'a' represent ?
Answer» SOLUTION :(i) Metal OXIDE of C (ii) Metal oxide of B (iii) Above temperature c (iv) CO (v) The change in STATE (at FUSION or vaporisation)
