Question #2: (35 Marks) Ammonia gas (NH3) is diffusing through nitrogen under steady-state conditions with nondiffusing N2. The mixture total pressure is 1.013x10 Pa and the temperature is 298K. The partial pressure of NH3 is 0.14x10 Pa at one end and at the other end 3 cm away it is 0.070x10Pa. At these conditions, the diffusivity of each component in the mixture is 2.30x10 m/s. Determine: a) The molar flux of NH3 b) The molar flux of NH, assuming that N, is also diffusing i.e considering an equimolar counter-diffusion. Which case a) or b) produces the highest flux and which one has the highest resistance to mass transfer c) Express the partial pressure of NHz in terms of the length z and determine the values of partial pressures of both gas at half way the total length, for each case a) and b)
