The lighter He atoms ( M = 4.00 g/mol) effuse through the small hole more rapidly than the heavier ethylene oxide (C 2 H 4 O) molecules ( M = 44.0 g/mol), as predicted by Graham’s law (Equation 10.8.1 ). At a given temperature, heavier molecules move more ... WebFeb 2, 2011 · The higher the pressure, the denser is the molecule packing, the less is the free-path length, and the slower is the diffusion. The same occurs as molecule mass and size increase. Conversely, elevation of temperature causes an increase in the free-path length, a decrease in the number of collisions, and growth of free-motion velocity. fitness smart band watch company china

Solution properties Graham later studied the diffusion of salts into liquids and discovered that the diffusion rate in liquids is several thousand times slower than in gases.

WebThe lighter gases pass through the small openings more rapidly (at a higher rate) than the heavier ones (Figure 9.29). In 1832, Thomas Graham studied the rates of effusion of different gases and formulated Graham’s law of effusion: The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles:
