For a solid-catalyzed reaction, the Thiele modulus is proportional to
- √(intrinsic reaction rate / diffusion rate)
- B√(diffusion rate / intrinsic reaction rate)
- Cintrinsic reaction rate / diffusion rate
- Ddiffusion rate / intrinsic reaction rate
Explanation
The Thiele modulus φ=(Rs/3)√(kρp/De) can be interpreted as the square root of the ratio of the intrinsic (surface) reaction rate to the diffusion rate through the pellet.
