Question

the order of RMS velocities of molecules ; n2,CO2,ch4and so2and

at a given temperature is:


​

Answer 1

Answer:

Note: The molar masses of CH4, He and SO2 are 16 g/mol, 4 g/mol and 64 g/mol respectively.

 r=M3RT=16×10−33RT:4×10−33RT:64×10−33RT

The molar masses in the above formula are substituted in kg.

 rCH4: rHe: rSO2=41:21:81=2:4:1

The R.M.S. velocity of CH4, He and SO2 are in the ratio of  2:4:1
