WebLecture 4 - The College of Engineering at the University of Utah WebFeb 12, 2024 · Fick’s First Law of Diffusion. Fick's first law of diffusion is given by the following equation: \[ J = -D \dfrac{dc}{dx} \label{1} \] where $J$ is the flux and is defined by the number or particles that are moving past a given region divided by the area of that region multiplied by the time interval. The units of $J$ are mol m -2 s-1. higate bathroom
