Question

Select the incorrect option for the Ellingham diagram ($\Delta G^{\circ }$ versus T).

• A. Positive value of ${\Delta }_f{G}^{\circ }for{M}_{x}O$ indicates, $M_{x}O$ decompose on its own
• B. Metal with most -ve value of $\Delta G^{\circ }$ for formation of oxide can act as a better reducing agent
• C. $\Delta G^{\circ }$ is plotted for the oxidation of metal with 1 mole of $O_2$
• D. $\Delta G^{\circ }$ is plotted for reduction of 1 mole of metal oxide

Answer 1

The correct option is D $\Delta G^{\circ }$ is plotted for reduction of 1 mole of metal oxide

$\Delta G^{\circ }$ is plotted for reduction of 1 mole of metal oxide
