WebDiffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration. Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices. The rates of effusion of gases are inversely proportional to ... WebFeb 26, 2016 · rateH2 = 4.15 ⋅ rateCO2 As predicted, hydrogen gas will effuse at a faster rate than carbon dioxide. Therefore, if it takes 32 s for carbon dioxide to effuse, and hydrogen effuses 4.15 times faster, you can say that you have tH2 = 32 s 4.15 = 7.7 s The answer is rounded to two sig figs. WebQuestion: 1. In an effusion experiment, 45 s was required for a certain number of moles of an unknown gas X to pass through a small opening into a vacuum.
