(Solution) - A gas mixture is found to contain two diatomic A -(2025 Original AI-Free Solution)

Paper Details

A gas mixture is found to contain two diatomic A and B species for which the partial pressures of both are 0.05065MPa (0.5atm). This mixture is to be enriched in the partial pressure of the A species by passing both gases through a thin sheet of some metal at an elevated temperature. The resulting enriched mixture is to have a partial pressure of 0.02026MPa (0.2atm) for gas A, and 0.01013MPa (0.1atm) for gas B. The concentrations of A and B (CA and CB, in mol/m3) are functions of gas partial pressures (pA2 and pB2, in MPa) and absolute temperature according to the following expressions: Furthermore, the diffusion coefficients for the diffusion of these gases in the metal are functions of the absolute temperature as follows:
Is it possible to purify the A gas in this manner? If so, specify a temperature at which the process may be carried out, and also the thickness of metal sheet that would be required. If this procedure is not possible, then state the reason(s)why.
