The square of Thiele modulus, Mₜ, is given byMₜ²=L² k/Deff, where L is the characteristic length of the catalyst pellet, k is the rate constant of a first order reaction, and Dₑ_f_fis the effective diffusivity of the species in the pores. Mₜis a measure of
Options
- A.
- B.rateofporediffusion/rateofreaction
- C.timescaleofreaction/timescaleofporediffusion
- D.timescaleofporediffusion/timescaleofreaction
Answer
CSolution
(M_t)^2 = /frac{L^2k}{D_e_f_f}
characteristicL/intrinsicrxⁿrate/Diffusionrate
Thiele modulus = reaction rate / diffusion rate
Time scale of the limiting transport mechanism
