Mass transfer co-efficient 'K' according to penetration theory varies with mass diffusivity as____________________?
Correct answer: C. D0.5
- A. 1/D
- B. D
- C. D0.5
- D. D1.5
Explanation
Penetration theory gives a mass-transfer coefficient proportional to the square root of diffusivity, typically expressed as k proportional to D raised to the power one-half. Thus, K varies as D0.5.
