For gaseous state, if most probable speed is denoated by `C^(**),` average speed by C and mean square speed by `barC,` then for a large number of molecules the ratios of these speeds are:

A

`C^(**) : C^(-) : C = 1 : 1.225 : 1.128`

B

`C^(**) : C^(-) : C = 1.225 : 1.128 : 1`

C

`C^(**) : C^(-) : C = 1.128 : 1.125 : 1`

D

`C^(**) : C^(-) : C = 1 : 1.128 : 1.125`

Text Solution

Verified by Experts

The correct Answer is:
D
`overset(**)(C)=sqrt((2RT)/(M)), bar(C)=sqrt((8RT)/(pi M)), C=sqrt((3RT)/M)`
`:. overset(**)(C): bar(Cl):C=sqrt(2):sqrt(8/pi):sqrt(3)=1:sqrt(4)/pi:sqrt(3/2)`
`=1:1.128:1.225`
