Chapter 14: External Diffusion Effects on Heteregeneous Reactions

Additional Homework Problems

CDP14-HB

  Read the section in Perry's Handbook on multicomponent diffusivities. Using the appropriate equations together with the Fuller correlation [E. N. Fuller, P. D. Schettler, and J. C. Giddings, Ind. Eng. Chem., 48(5), 19 (1966)], calculate the diffusivities of SO2, O2, N2, and SO 3 when the reaction
