For an equimolar mixture of CO2 and CH4 gases (Landfill gas composition) at 800 K, prepare plots of log D vs. log P for the overall macropore diffusion coefficient, considering Molecular and Knudsen diffusion as the mass transfer mechanisms. Consider pressures between 0.00001 and 1,000,000 atm. Do the plots for pore sizes of 1 (mu), 0.1 (mu), 0.01 (mu), and 1 . Comment on the observed changes in the diffusivity with respect to pressure and with pore size

If possible show all the formula
