Mass Transfer

Q1:

In case of liquids, the binary diffusivity is proportional to (where, T = temperature)

A T

B T

C T2

D 1/T

ANS:A - T

In the case of liquids, the binary diffusivity (𝐷D) is typically inversely proportional to temperature (𝑇T). Mathematically, this relationship is expressed as: 𝐷∝1𝑇D∝T1​ This means that as the temperature (𝑇T) increases, the binary diffusivity (𝐷D) decreases, and vice versa. Therefore, the correct answer is: 1𝑇T1​
