A mixture of nitrogen and hydrogen are diffusing through a membrane at 1 atm and 293 K. Calculate the pore diameter of the membrane if the diffusivity of hydrogen in nitrogen is 74.3 x 10“ m³/s at 288 K and effective diffusivity of hydrogen through nitrogen is 5.3 x 10“ m²/s at 293 K and effective Knudsen diffusivity of hydrogen is 11.7 x 10“ m²/s at 293 K.
