Question

only #13-15

13. Order the following species from fastest diffusers to slowest diffusers at STP. N2, CO2, UF6, N2O2, Cl2 14. How much faster does O2(g) move than WBr4 (g) at 485 °C? 15. How much faster does H2 (g) move than UF6 (g) at STP? 16. How many a) molecules of N2 and b) atoms of N are in a 7,450 mL container at 33.9 °C while under

Answer 1

di 137. Mate of ilusion a l U Molar mass bastest diffusion. If Molar wass is less then Mate al Molar mass Molar mass of N = 28 gm /mol Molar mass of co= 44 gmirol Uff = 352 gol mol N202 = 60 gr/mol ų = 71 glmet Hence rate of diffusion : N₂ 7 CO 2 7N2027 U2 7 UF N₂ diffuses fastest, while ufo diftuses slowest. JAY. rate of 2 lg) = 1 U Molar mass of 2 rate of WBra 197= 1 Molar mass of WBA fat constant and Equal Temp. - Mate of 2 rate of Wera Molar mass of why WBr4 V Molar mass at 0₂ 32 = 3.96 rale of 02 rate of worq rate of 02 = 3.96 times rate of wBra

rate of H2 = UMolar mass of 42 rate of ufo = L Molar mass of uff rak of H2 12 rate of UF V Molar mass of off Molar mass of 2 a rate of H₂ - 352 min rate of Ufo 12 & rase of 42 = 13.27 rad of UF I rate of the = 13.27 times that of rate of UFO
