<center><b>Graham's Law of Diffusion</b></center> <br> <b>Remember, <nowiki>Write the law with subscript of gases and always show rate of diffusion ratio with subscripts. SIG FIGS - TWO PLACES AFTER DECIMAL</nowiki></b><br> <br> 1. What is the relative rate of diffusion of carbon dioxide gas to nitrogen gas?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. How many times faster is hydrogen gas to chlorine gas (both gas are in elemental form)? <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. What is the relative rate of diffusion of nitrogen dioxide and ammonia gas? <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Answer: 1) r<sub>N2</sub>/r<sub><nowiki>CO</nowiki>2</sub> =1.25 or r<sub><nowiki>CO</nowiki>2</sub>/r<sub>N2</sub>=0.80<br>2) r<sub>H2</sub>/r<sub>Cl2</sub> = 5.96<br>3) r<sub><nowiki>NH</nowiki>3</sub>/r<sub><nowiki>NO2</nowiki></sub> = 1.64 or r<sub><nowiki>NO2</nowiki></sub>/r<sub><nowiki>NH3</nowiki>N2</sub>=0.61
