Question

Which gas has highest most probable velocity?

Answer 1

Answer:

For example, many molecules have speeds around 500 m/sec, whereas few molecules have speeds around 1000 m/sec. The speed that corresponds to the peak of the curve is called the most probable speed. More molecules travel at (or close to) this speed than any other. For N2 at 25ºC, the most probable speed is 421 m/

Answer 2

Explanation:

Observe that the gas with the lowest molar mass (helium) has the highest molecular speeds,
