Chapter 14: External Diffusion Effects on Heteregeneous Reactions

Additional Homework Problems

CDP14-LB

The oxidation of ammonia is to be carried out over a platinum gauze. The molar flow rate of ammonia is 10 mol/min at a temperature of 500 K and a pressure of 202.6 kPa. Is one 250-mesh screen 10 cm in diameter sufficient to achieve 60% conversion? The wire diameter is 0.044 mm. Assume 25% excess air, and ignore the effects of volume changes on the Reynolds number.
