The Knudsen diffusivity is proportional to (where, T = absolute temperature) ______________________?
Correct answer: A. √T
- A. √T
- B. T2
- C. T
- D. T4
Explanation
Knudsen diffusivity is governed by molecular speed inside the pores: D_K is proportional to √(T/M). For a fixed gas, this means it varies as √T.
