A) 2 : 1
B) 4 : 5
C) 1 : 1
D) 1 : 2
Correct Answer: C
Solution :
\[\text{KE =}\,\frac{3}{2}nRT\] \[KE\propto n\] \[KE\propto \frac{w}{M}\] \[\frac{{{K}_{{{H}_{2}}}}}{{{K}_{He}}}=\frac{{{M}_{He}}}{{{M}_{{{H}_{2}}}}}=\frac{2}{2}=\frac{1}{1}\] \[K{{E}_{{{H}_{2}}}}:K{{E}_{He}}=-1:1\]You need to login to perform this action.
