Question: 3. a) Derive D = 4x using solid state diffusion theory b) Calculate the binary O2/N2 gas diffusivity at T = 300K and compare

3. a) Derive D = 4x using solid state diffusion theory b) Calculate the binary O2/N2 gas diffusivity at T = 300K and compare it to the pure 02 self- diffusivity. The molecular diameter of N2 is approximately 3.2A and that of oxygen is 3.0A. The self diffusivity of Oz is 0.165 cm/s.
