In case of liquids, the binary diffusivity is proportional to (where, T = temperature)
A. T
B. $$\sqrt {\text{T}} $$
C. T2
D. $$\frac{1}{{\text{T}}}$$
Answer: Option A
Solution (By Examveda Team)
Binary diffusivity in liquids primarily depends on the temperature, and for liquids, it is directly proportional to the temperature.The relationship of binary diffusivity with temperature differs between gases and liquids.
For gases, binary diffusivity (D) is proportional to T3/2/P, where P is pressure.
However, in liquids, binary diffusivity is proportional to T as temperature changes have a more direct impact due to the close molecular interactions in liquid phases.
