Diffusivity in concentrated solutions differs from that in dilute solutions, because of the changes in ____________________?
Correct answer: B. Both A. and B.
- A. Viscosity with concentration
- B. Both A. and B.
- C. Degree of ideality of the solution
- D. Neither A. nor B.
Explanation
In concentrated solutions, diffusivity is affected by both concentration-dependent viscosity and departures from ideal solution behaviour. Dilute-solution correlations usually neglect these coupled effects, so both factors matter.
