medium
Correct for the following graph is/are
A
$Mg$ will be good reducing agent below $1673\,K$
B
$Al$ will be good reducing agent below $1673\,K$
C
$Al_2O_3$ will be good reducing agent after $1673\,K$
D
Both $(A)$ & $(C)$
Solution
$\Delta {\text{G}}_{{\text{MgO}}}^o < \Delta {\text{G}}_{{{\text{A}}_2}{{\text{O}}_3}}^o$ below $1673\,{\text{K}}$
$Mg$ will be good reducing agent below $1673\,\mathrm{K}$
