Which of the foll A. hydrogen

B. nitrogen

C. oxygen

D. carbon dioxide

Answer :

Rms speed at given temperature is given as


vrms =


where R=gas constant whose value is 8.31 J/mol K.


T=temperature of gas.


M= molar mass of molecule of gas


Therefore, at a given temperature rms speed of gas is inversely proportional to square root of molar mass of molecule of that gas.


Out of the four-option molar mass of hydrogen molecule is least


i.e. 2 amu. So rms speed of hydrogen will be maximum.
