Which will diffuse faster ,ammonia or CO_{2}? what are their relative rates of diffusion.

2. Density for Ammonia(gas) at STP is 0.73 kg/m

^{3}and for Carbon dioxide is 1.98 kg/m

^{3}.

3. Thus,as CO

_{2}will diffuse faster due to higher density as compared to NH

_{3}.

4. Relative Rate of Diffusion :

$\frac{{r}_{N{H}_{3}}}{{r}_{C{O}_{2}}}=\frac{\sqrt{{m}_{C{O}_{2}}}}{\sqrt{{m}_{NH3}}}=\sqrt{\frac{17.0}{44}}=0.38$
