Precisely `1 mol` of helium and `1 mol` of neon are placed in a container. Indicate the correct statements about the system.

Options

A. Molecules of the two gases strike the wall of the container with same frequency.
B. Molecules of helium strike the wall more frequently.
C. Molecules of helium have greater average molecular speed.
D. Helium exerts larger pressure.

Explanation

Hint: Helium gas has lower molecular mass and hence it moves faster than neon and strikes the wall more frequently.
`mu_(av)=sqrt((8RT)/(pi M))`
`mu_(av) prop ((1)/(M))^(1//2)`
Hence. `He` has higher speed than neon.
