Question:
According to the following diagram, A reduces $BO_2$ when the temperature is :
According to the following diagram, A reduces $BO_2$ when the temperature is :
Updated On: Jul 20, 2024
- $> \,1200\,^{\circ}C$ but $< 1400\, ^{\circ}C$
- $>\, 1400 \,^\circ C$
- $< 1200\, ^\circ C$
- $<1200 \, ^\circ C$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A reduces $BO_{2}$ when temperature is above $1400^{\circ}C$ because above $1400^{\circ}C$ A has more - ve $\Delta G^{\circ}$ for $AO_{2}$ formation than B to $BO_{2}$ formation.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
