Derive fick's second law
WebFeb 12, 2024 · Using Fick's second law: First, rearrange the equation T = x 2 /2D to solve for D --> D = x 2 /2T Where: D = our unknown (diffusivity constant) x = 0.01 cm (distance from the outside to the center of the cell) T = 5s D = (0.01cm) 2 / [2 (5s)] D = 1×10-5cm2/s References Chang, Raymond. Physical Chemistry for the Biosciences. WebFick's second law is a differential equation with a solution the describes the concentration of a contaminant as a function of position and time, when the contaminant is only subjected to diffusion. Recall that Fick's 1st law, which describes diffusive flux F in a …

WebThe differential form of Fick’s second law is the basic equation for the study of isothermal diffusion. Derivation of Fick’s Second Law: Consider an elemental slab of thickness Ax along the diffusion distance x. Let the slab X- section be perpendicular to x and its area be unity. The volume of the slab is then ∆x x 1 = ∆x. WebNov 29, 2024 · We assume the rate of diffusion is proportional to the concentration gradient, a relationship known as Fick’s law of diffusion. Fick’s law of diffusion assumes the mass flux J, with units [ J] = m / t across a cross section of the pipe is given by (9.1.1) J = − D u x,
