SO_2 and CH_4 are introduced in a vessel in the molar ratio 1:2.The ratio of molecules of two gases present in the container when their rate of effusion becomes equal is :

Answer»

`1:2`
`2:1`
`4:1`
`1:4`

SOLUTION :`r=prop p/sqrtM`
`p_1/sqrtM_1=p_2/sqrtM_2`
`p_1/p_2=sqrtM_1/sqrtM_2=n_1/n_2 IMPLIES n_(SO_2)/n_(CH_4)=SQRT(M_(SO_2)/M_(CH_4))=sqrt(64/16)=2`
