Fick’s first law tells us HOW MUCH flux to expect. Fick’s second law gets into more detail, telling us the rate at which concentration is changing at any given point in space. This law takes the form of a “partial differential equation”, that is, an equation that allows us to solve for rates involving both time and space. the palace lofts denver
