Consider a hydrogen (A) diffusion in two different medium (i) air

Consider a hydrogen (A) diffusion in two different medium (i) air (B) and (ii) liquid water (B) at 293K and 1atm. The concentration gradient in both processes at a particular location is dxdCA=7102mm3kmol. Calculate the species diffusive flux on both molar and mass bases for both cases. Here, the mole fraction of the hydrogen is much less than unity. Given Data: Diffusion coefficient of hydrogen in air at 298K and 150KPa is 0.41104m2/s Diffusion coefficient of hydrogen in water at 323K and 1 atm is 0.63108m2/s. Gas constant =8.314m3PaK1mol1
