Question

Refer to Q4, and calculate the diffusivity of O2 in a gas mixture.

(a) 1.539×10^-5 m^2/sec

(b) 1.639×10^-5 m^2/sec

(c) 1.530×10^-5 m^2/sec

(d) 1.630×10^-5 m^2/sec

I had been asked this question in an interview for job.

Question is from Molecular Diffusion topic in chapter Mass Transfer of Bioprocess Engineering

Answer 1

The correct answer is (a) 1.539×10^-5 m^2/sec

To explain: Diffusivity of O^2 in the mixture,
