Question:
According to the following diagram, A reduces $\mathrm{BO}_{2}$ when the temperature is :
Correct Option: , 2
Solution:
A reduces $\mathrm{BO}_{2}$ when temperature is above $1400^{\circ} \mathrm{C}$ because above $1400^{\circ} \mathrm{C}$ A has more ve $\Delta \mathrm{G}^{\circ}$ for $\mathrm{AO}_{2}$ formation than $\mathrm{B}$ to $\mathrm{BO}_{2}$ formation.
