Molar mass of B₂H₆ = Molar mass of C₂H₄ = 28.

Density = $\frac{wt}{v o l u m e}$ .

K.E. = $\frac{3}{2} n RT$ .

Rate of effusion $\propto \frac{P}{M}$ .

$\frac{r _{B_{2} H_{6}}}{r _{C_{2} H_{4}}} = \frac{p _{B_{2} H_{6}}}{p _{C_{2} H_{4}}} \cdot \frac{2 T}{T} = \frac{1}{2} \times 2 = \frac{1}{2}$

$v_{r m s} \propto T$
