Observe the following data and match the following questions to correct answers. each answer can be used more than once or not at all. refrigerated set refrigerated set room temp set room temp set solute (dye) molecular weight distance in mm rate distance in mm rate potassium dichromate 294 8 .533 mm/hr 38 2.53 mm/hr malachite green 364 5 .333 mm/hr 21 1.4 mm/hr aniline blue 738 3 .200 mm/hr 13 .866 mm/hr dye with low molecular weight moves faster. movement of solute molecules is faster at lower temperature. this experiment is an example of temperature can affect rate of diffusion. aniline blue diffuses at a slower rate because of its low molecular weight a. true b. false c. diffusion d. osmosis

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
