<prompt> Ficks law, flux of Geomembrane increased in:Concentration acrossTemperatureIncreased size of moleculeWeight  <response>: A i.e. Concentration acrossAccording to Ficks law of diffusion, the net rate of diffusion is directly propoional to available surface area across which diffusion is taking place and the concentration or chemical gradient but inversely propoional to thickness of membraneQ.Ficks Law of DiffusionThe magnitude of diffusing tendency is directly propoionate to the cross sectional area across which diffusion is taking place and the concentration gradient or chemical gradient , which is the difference in concentration of the diffusing substance divided by the thickness of boundary.
