a. What is diffusion? b. What factors affect the rate of diffusion of one gas through another?
What are the ratios of the diffusion rates for the pairs of gases (a) $\mathrm{N}_{2}$ and $\mathrm{O}_{2} ;$ (b) $\mathrm{H}_{2} \mathrm{O}$ and $\mathrm{D}_{2} \mathrm{O}$ $\left(D=\text { deuterium, i.e., }_{1}^{2} \mathrm{H}\right) ;(\mathrm{c})^{14} \mathrm{CO}_{2}$ and $^{12} \mathrm{CO}_{2}$;(d) $^{235} \mathrm{UF}_{6}$ and $^{238} \mathrm{UF}_{6} ?$
1. Under conditions in which the density of CO2 is 1.96 g /L and that of N2 is 1.25 g/L, which gas will effuse more rapidly? What will be the ratio of the rates of effusion of N2 to CO2? 2. Arrange the following gases in order of increasing rate of diffusion at 25 °C: Cl2, C2H4, SO2. Explain your reasoning for the ranking. 3. An unknown gas X effuses 1.65 times faster than C3H8. What is the molecular mass of gas X?
