The Thiele modulus compares

  • A.the external and the internal surface areas
  • B.the reaction rate with the flow rate
  • C.the catalyst mass with the reactor volume
  • D.the intrinsic rate with pore diffusion

Answer: D

Correct answer: the intrinsic rate with pore diffusion

\[ \phi = L\sqrt{\frac{k}{D_{eff}}}, \] a ratio of the rate at which reactant would be consumed to the rate at which it can diffuse into the pellet. A small value means diffusion keeps up and the whole pellet is used; a large value means the reaction is finished near the outside.
