Question: 2 nickel carbonyl component b is produced by passing carbon...

Question details

2. Nickel carbonyl (component B) is produced by passing carbon monoxide (component A) over nickel. The following reaction takes place at the solid surface Ni + 4CO(g) -Ni(CO)4(g) a) Assume the reaction is very rapid ()so that the partial pressure of CO at the metal surface is essentially zero. Therefore, the rate of carbonyl formation is limited by the rate of CO diffusion to the nickel surface. The gas outside the diffusion layer (δ = 0.695 mm) is pure CO, the temperature and pressure of the system remains constant at 50°C and 1.0 atm, respectively, the area of the nickel is 0.25 m2, and DAB 2.0 x 105 m/s. Calculate the reaction rate of nickel carbonyl in kmol/s. Assume steady state behavior and ignore changes in the nickel metal.
