Nickel carbonyl (component b) is produced by passing carbon monoxide (component a) over 1. a nickel surface. the following reaction takes place at the solid surface. ni + 4co(g) ni(co)(g) the gas outside the diffusion layer () is pure co (a-1.0), 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 × 10-5 m12/s. assuming steady-state behavior and ignoringchanges in the nickel metal, the diffusional flux of co towards the nickel is given by: (20 points) 1-xa2 381 for a diffusion-limited reaction, circle the answer that best describes the result increasing the area of the nickel will: a. increase the reaction rate b. decrease the reaction rate c. have no affect on the reaction rate d. have an effect, but there's not enough information to know what it would do increasing the diffusion layer thickness will: increase the reaction rate a. b. decrease the reaction rate have no affect on the reaction rate have an effect, but there's not enough information to know what it would do c. d. increasing the temperature of the system will: a. increase the reaction rate b. decrease the reaction rate c. have no affect on the reaction rate d. have an effect, but there's not enough information to know what it would do increasing the total pressure of the system will: a. phcrease the reaction rate decrease the reaction rate c. have no affect on the reaction rate d. have an effect, but there's not enough information to know what it would do
