Increasing order of rms velocities of $H_{2}, O_{2}, N_{2}$ and $HBr$ is

Options:

Answer:

Solution:

RMS velocity of molecules depends on mass. If mol. wt. increases, rms velocity of melocules decreases. $rms \propto \frac{1}{m \cdot wt}$ The order of increasing $m . wt$ . is $H_{2} < N_{2} < O_{2} < HBr$ Order of $V_{mx}$ of molecules. $HBr < O_{2} < N_{2} < H_{2}$
