Vedclass · Answer

(D) In the Ellingham diagram,the slope of the line for the oxidation of a metal $(M \rightarrow MO)$ changes when the metal undergoes a phase change (melting or boiling). Looking at the provided diagram,the line for $M \rightarrow MO$ shows a distinct change in slope at a certain temperature. This change in slope indicates a phase transition of the metal $M$. Since the reaction $MO(s) + C(s) \rightarrow M(?) + CO(g)$ occurs at temperatures where the metal $M$ is produced,the physical state of $M$ depends on whether the temperature is above or below its melting or boiling point. Typically,such a change in slope in an Ellingham diagram corresponds to the melting of the metal. Therefore,the metal $M$ can exist as a solid or a liquid depending on the temperature range relative to its melting point.

Predict the physical state of the metal $M$ obtained in the following reduction reaction shown by the Ellingham diagram: $MO(s) + C(s) \rightarrow M(?) + CO(g)$.
