1. Estimate the effective diffusivity of hydrogen in ethane in a porous solid with an average pore size of 4000 Å, 40% porosity, and tortuosity of 2.5. The gas mixture is at a pressure of 10 atm and a temperature of 373 K. For this system, the ordinary diffusion coefficient is given by DAB = 0.86/P in cm²/s with total pressure P in atm. The collision diameters for hydrogen and ethane are 2.827 and 4.443 A respectively. O
