The Ellingham diagram for zinc, magnesium and carbon converting into corresponding oxides is shown below.

At ........ $^oC$ temperature, zinc and carbon have equal affinity for oxygen .

$1000$

$1500$

$500$

$1200$

Solution

As both oxides of zinc and carbon, i.e., $ZnO$ and $CO$ met at $1000^{\circ} C$ in graph, so at this temperature, both carbon and zinc have equal affinity with oxygen.

$FeC{r_2}{O_4}$ (chromite) is converted to $Cr$ by following steps :

Chromite $\xrightarrow{I}NaCr{O_4}\,\,\xrightarrow{{II}}\,C{r_2}{O_3}\,\xrightarrow{{III}}\,Cr$

Reagents in $I,\,II$ and $III$ step might be
