MEDIUMMCQ SINGLEIChO (Chemistry Olympiad)Physical ChemistryGaseous stateMaxwell's distribution of molecular speeds
By which factor does the root mean square velocity of a gaseous molecule increases, when the temperature is increase from 273 K to 1092 K.
A.4
B.1.4
C.2✓ Correct
D.0.5
Explanation
rms 3RT v M i.e., rms v T 1 1 2 2 V T V T >> 1 2 V 273 1 V 1092 2 >> 2 1 v 2v >> Rms speed increases by 2 times.
