Q.1 A gas of CH4 is diffusing under steady state condition through a tube containing nitrogen gas. The partial pressure of CH4 at point 1 is pAI = 55 kPa and at point 2, 0.03 m apart PA2 = 15 kPa. The total pressure is 101.32 kPa, and the temperature is 298 K. At this pressure and temperature, the value of diffusivity is 6.75x10-5 m²/sec. R = Universal gas constant (8.314 J/mol. K). i) Find the flux of methane at steady state for equimolar counter diffusion. ii) Calculate the partial pressure at a point 0.02 m apart from point 1.
