Water(A) evaporates from a cylindrical container to stagnant air (this is diffusion of A through a nondiffusing B or unimolecular diffusion). The water level is kept constant and the L distance (between the water surface and tube edge) is 10cm. 1. (1 point) Starting from the general equation NA=(NA+NB)CCADABzCA derive, for this example, the flux solution: NA=LDABRTPln(1PPcap,A) 2. (0.5 points) Calculate the flux (NA) for this system at: - 25C and 1atm - 50C and 1atm Note that you will have to look for property data (diffusion coeff and vapor pressure).
