WebTherefore, they have higher melting and boiling points compared to covalent compounds. How do you determine the highest and lowest boiling point? Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. WebDec 8, 2024 · Solution To find the temperature change elevation of a solvent by a solute, use the equation: ΔT = iK b m where: ΔT = Change in temperature in °C i = van't Hoff factor K b = molal boiling point elevation constant in °C kg/mol m = molality of the solute in mol solute/kg solvent Step 1. Calculate the Molality of the NaCl
