A lab studies diffusion of a small nonpolar anesthetic across a lipid bilayer. The membrane is modeled as a slab of thickness LL with steady-state flux J=−D ΔC/LJ = -D\,\Delta C/L. Two membranes have identical composition and temperature, but Membrane X is twice as thick as Membrane Y. If the same concentration difference ΔC\Delta C is imposed across each, which prediction is most consistent with Fick's law for the steady-state flux?
