Carbon dioxide at 20°c and 3 bar is held in a 5 l vessel. the vessel is sealed with a rubber plug of 10 mm thickness. estimate the mass flux of co2 through the plug, and (0) (ii) the partition coefficient of coarubber given d 1 x 10-10 m2 s1 (this is the diffusion coefficient of co2 through the rubber) cco2 4 kg m3 (this is the concentration of co2 just in the rubber plug on the co2 side of the plug)
