Oxygen is diffusing through a stagnant layer of methane 10 mm thick. The temperature is 20°C and the pressure 100 kN/m2. The concentrations of oxygen on the two sides of the film are 15% and 5% by volume. The diffusivity of oxygen in methane at 20°C and 100 kN/m2 is 2.046 x 10-5 m2/s. (i) Calculate the rate of diffusion of oxygen in kmol/m2s
