Vedclass · Answer

(D) In the steel industry,using pure $O_2$ instead of air provides several advantages:$1$. Faster reaction rates: Since air contains about $78\%$ nitrogen,which acts as a diluent,using pure $O_2$ increases the concentration of the reactant,leading to faster oxidation of impurities and higher production rates $(I)$.$2$. Efficiency: Because the volume of gas handled is reduced (no nitrogen to heat or process),larger quantities of steel can be processed in the same equipment $(II)$.$3$. Product Quality: Air contains nitrogen,which can react with molten steel to form nitrides,making the steel brittle. Using pure $O_2$ eliminates this,resulting in a purer product free from nitrides $(III)$.

The advantage$(s)$ of using $O_2$ rather than air in the steel industry is(are):
$(I)$ There is a faster conversion,so a given plant can produce more steel in a day.
$(II)$ Larger quantities can be handled.
$(III)$ It gives a purer product,and the surface is free from nitrides.
