A 4.1 molar mixutre of He and CH_(4) is contained in a vessel at 20 bar pressure. Due to a hole in the vessel, the gas mixture leeks out. What is the composition of the mixutre effusing out initially ? |

Answer» Solution :Molar ratio of He and `CH_(4)` is 4:1 `THEREFORE` Partial PRESSURE ratio of He and `CH_(4)` is 16:4 (`because` total pressure =20 bar) `(n_(He))/(n_(CH_(4)))=sqrt((M_(CH_(4)))/(M_(He)))xx(P_(He))/(P_(CH_(4)))` (`because` TIME of diffusion for both is same) `=sqrt((16)/(4) xx(16)/(4))=8:1` The COMPOSITION of mixutre initially gone out for He and `CH_(4)` is 8:1 |
