Question

What is the value of diffusivity for benzene?

(a) 0.055

(b) 0.066

(c) 0.077

(d) 0.088

This question was addressed to me during an online interview.

Question is from Diffusivity at 25 Degree Celsius and 1 atm Pressure in division Modes and Diffusion of Mass Transfer

Answer 1

Right answer is (d) 0.088

To explain I would say: It is having higher diffusivity so they diffuse faster into each other. Its unit is cm^2/s.
