Molten steel at 1900 K having dissolved hydrogen needs to be vacuum degassed.
The equilibrium partial pressure of hydrogen to be maintained to achieve 1 ppm (mass basis) of dissolved hydrogen is _____ Torr (rounded off to two decimal places).
Given: For the hydrogen dissolution reaction in molten steel (½ H
(g) = [H]), the equilibrium constant (expressed in terms of ppm of dissolved H) is:
1 atm = 760 Torr
