C2H2 has an effusion rate of 0.00114mol/sec. Which of the gases below would have an effusion rate of 0.00129mol/sec?CO2COCl2CH3ClH2SNeChemistry and Chemical ReactivityKotz and Treichel;Thomson PublishingChapter 12.7Lecture Help Main PageFeedback to Dr Van BramerFeedback to George Wiger

The effusion rate of a gas is inversely proportional to the square root of its molar mass. This is known as Graham's law of effusion.

Given that the effusion rate of C2H2 is 0.00114 mol/sec, we can find the molar mass of C2H2. The molar mass of C2H2 (Acetylene) is approximately 26 g/mol.

The gas with an effusion rate of 0.00129 mol/sec will have a lower molar mass than C2H2.

Let's calculate the molar mass for each of the given gases:

1. CO2 (Carbon Dioxide): The molar mass is approximately 44 g/mol.
2. COCl2 (Phosgene): The molar mass is approximately 99 g/mol.
3. CH3Cl (Methyl Chloride): The molar mass is approximately 50 g/mol.
4. H2S (Hydrogen Sulfide): The molar mass is approximately 34 g/mol.
5. Ne (Neon): The molar mass is approximately 20 g/mol.

Among these gases, Neon (Ne) has the lowest molar mass. Therefore, Ne would have an effusion rate of 0.00129 mol/sec.
