Indicate the correct statement for equal volumes of `N_(2)(g)` and `CO_(2)(g)` at `25^(@)C` and 1 atm.

Options

A. The average translational K.E. per molecule is the same for `N_(2)` and `CO_(2)`
B. The rms speed is same for both `N_(2)` and `CO_(2)`
C. The density of `N_(2)` is less than that of `CO_(2)`
D. The total translational K.E. of both `N_(2)` and `CO_(2)` is the same

Answer

a,c,d

Explanation

(a,c,d) `KE=(3)/(2)RT(1"mole")U_(rms)=sqrt((3RT)/(M_(w)))`
`d=(PM_(w))/(RT)`
