A Basic Oxygen Furnace operator, at the end of oxygen blow, measures the dissolved oxygen content in the steel as 0.03 wt.% and the steel temperature as 1800 K. The carbon content [C] in the steel is ______ wt.% (round off to two decimal places).
Assume:
Equilibrium between dissolved carbon [C], dissolved oxygen [O], and CO (gas) at 1 atmosphere.
Henry’s law is valid for both [C] and [O]
Given:
[ C ]
+ [ O ]
→ (CO)
R = 8.314 J·mol
