WebDec 9, 2024 · r (M)½ = constant In these equations, r = rate of diffusion or effusion and M = molar mass. Generally, this law is used to compare the difference in diffusion and effusion rates between gases, often denoted as Gas A and Gas B. It assumes that temperature and pressure are constant and equivalent between the two gases. WebTo calculate how much work a gas has done (or has done to it) against a constant external pressure, we use a variation on the previous equation: \text {work}=\text w = - \text P_ {\text {external}} \times \Delta \text V work = w = −Pexternal × ΔV
