Lets consider a container with a volatile liquid A at room temperature and atmospheric pressure. There is no A in the air of the room. We are interested in calculating the flux of A out of the container. The flux can be described by: NA,z=z2z1DABln(1cA,11cA,2) where z2 and cA,2 are at the top of the beaker and z1 and cA,1 at the liquid/gas interface. Match the boundary conditions for cA,1 and cA,2 Lets consider a container with a volatile liquid A at room temperature and atmospheric pressure. There is no A in the air of the room.
