Methane gas is diffusing in a straight tube 0.1 m long containing helium at 298 k and a total pressure of 1.01325 x 10^5 Pa. the partial pressure of CH4 is 1.400 x 10^4 Pa at one end and 1.333 x 10^3 at the other end. Helium is insoluble in one boundary, and hence is non diffusing or stagnant. Calculate the flux of methane in kg mol/s m^2
