Q1:

In case of gases, the binary diffusivity is proportional to (where, P = pressure)

A P

B 1/P

C 1/P

D P

ANS:B - 1/P

In the case of gases, the binary diffusivity (𝐷𝐴𝐵) is typically inversely proportional to pressure (𝑃). This relationship is expressed by the following equation: 𝐷𝐴𝐵∝1𝑃 So, the correct option is: b) 1𝑃
