Suppose a layer of oil is on the top of a beaker of water. water in many oils is slightly soluble, so its concentration is so low that we can treat it as an ideal solute. suppose that at 283 k, the equilibrium concentration is 9 × 10-4 water molecules per oil molecule, and it takes 2.208 × 10-20 j to transfer one water molecule into the oil. what is the equilibrium concentration at 293 k, assuming that nothing else changes?
