Problem 2: Nickel carbonyl (A) is produced by passing carbon monoxide (B) at 323K and 1atm over a nickel slab. The following reaction takes place at the solid surface: Ni(s)+4CO(g)Ni(CO)+(g) The reaction is very rapid, so that the partial pressure of CO at the metal surface is essentially zero. The gases diffuse through a film with a thickness L=0.625mm. Estimate the rate of production of nickel carbonyl, in mole/ /cm2 of solid surface at steady state. The composition of the bulk gas phase (z=0) is 50mol%CO. The binary diffusivity is DAB=20.0mm2/s. Determine the concentration profile (mole fraction as a function of position) Problem 2: Nickel carbonyl (A) is produced by passing carbon monoxide (B) at 323K and 1atm over a nickel slab.
