A) \[\alpha :v:u::1:1.128:1.224\]
B) \[\alpha :v:u::1.128:1:1.224\]
C) \[\alpha :v:u::1.128:1.224:1\]
D) \[\alpha :v:u::1.124:1.228:1\]
Correct Answer: A
Solution :
\[{{V}_{av}}:{{V}_{rms}}\]: Vmost probable = \[V:U:\alpha \] \[\sqrt{\frac{8RT}{\pi M}}:\sqrt{\frac{3RT}{M}}:\sqrt{\frac{2RT}{M}}\] \[\alpha :V:U=\sqrt{2}:\sqrt{\frac{8}{\pi }}:\sqrt{3}\] \[=1:1.128:1.224\]
