Unformatted text preview: effusion of nitrogen gas under the same conditions? Effusion A sample of Ne gas effused through a pinhole and took 38.0 s. How long will it be for the same amount of Kr to effuse under the same conditions? A sample of unknown gas effused at a rate that is 0.462 times that of nitrogen gas. What is the molecular weight of the unknown gas? Effusion In the real world, the behavior of gases only conforms to the ideal-gas equation at relatively high temperature and low pressure . Real Gases nitrogen gas The assumptions made in the kinetic-molecular model break down at high pressure and/or low temperature. Real Gases The van der Waals Equation...
