Question
Chemistry Question on General Principles and Processes of Isolation of Elements
According to the following diagram, A reduces BO2 when the temperature is :
A
>1200∘C but <1400∘C
B
>1400∘C
C
<1200∘C
D
<1200∘C
Answer
>1400∘C
Explanation
Solution
A reduces BO2 when temperature is above 1400∘C because above 1400∘C A has more - ve ΔG∘ for AO2 formation than B to BO2 formation.
