At a different location an effectively infinite amount of each of the 3 compounds is buried in the ground covered by 3 meters of soil. The temperature is 25 degrees C. Estimate the flux density of Toluene to the atmosphere by vapor diffusion and towards the groundwater by dissolving in the infiltrating water in units of kg, meters, and seconds. We are separating the two processes in order to keep the problem simple. Make a figure with coordinate system. Give the sign of the flux.
Signs are opposite but depend upon coordinate system.
