Question #13682

What is the rms speed of N2 molecules at 389 K?

Expert's answer

The root-mean-square speed is given by:

v_rms = √(3∙R∙T/M)

(R universal gas constant, T absolutte temperature, M molar

mass)

v_rms = √(3*8.31* 398/0.028) = 589 m/sec

v_rms = √(3∙R∙T/M)

(R universal gas constant, T absolutte temperature, M molar

mass)

v_rms = √(3*8.31* 398/0.028) = 589 m/sec
