Quizplus · Accepted Answer

Fick's law states that the rate of diffusion of a gas in a gaseous medium is directly proportional to the concentration gradient. This means that as the concentration gradient increases, the rate of diffusion will also increase. Henry's law deals with the solubility of a gas in a liquid and is not relevant to this question. Dalton's law describes the partial pressures of gases in a mixture, while Graham's law describes the rates of effusion or diffusion of gases through a porous barrier. Thus, A) Fick's law is the best choice for this question.
