When octane is mixed with methanol, the vapor pressure of octane over the solution is higher than we would calculate using Raoult's law. Why? Explain the discrepancy in terms of intermolecular attractions. Explain by selecting all that apply. O This is called a negative deviation from Raoult's law. O This is called a positive deviation from Raoult's law. O This occurs when the solvent-solute intermolecular attractions are larger than the attractions between molecules in the pure solvent and molecules in the pure solute. O This occurs when the solvent-solute intermolecular attractions are smaller than the attractions between molecules in the pure solvent and molecules in the pure solute. O None of these.
