Q. During decarburization in a steel bath at 1550 oC, the compositions of dissolved C (wt.%C) and dissolved O (wt.%O) follow the relation: (wt.%C)(wt.%O) = K When the partial pressure of CO (๐๐ถ๐) is 1 atm, K = 0.002. If ๐๐ถ๐ = 0.1 atm, what is the value of K, at the same temperature? Note: Assume Henryโs law is applicable.
(A) 0.06 (B) 0.002 (C) 0.02 (D) 0.0002
Ans: 0.0002
