A vapor consists of chloroform CHCl3 and carbon tetrachloride CCl4. The temperature and the pressure

amounts or 62.9 C and 760 mm Hg. The diffusivity in the gas phase is 3.545*10(-6) m^2/s.

Furthermore are given:

critical pressures: chloroform 53.9 atm; carbon tetrachloride : 45 atm

critical temperatures : chloroform 533 K ; carbon tetrachloride 556 K

- In such a gas phase, at a certain moment a concentration gradient of 0.5 mol%

chloroform per m observed. What is the flux in mol/(m2.s) to chloroform due to this

gradient under stationary conditions?

Answer: N= 6.43*10^(-7) mol/(m^2.s)
