WebAug 25, 2024 · The van’t Hoff factor is therefore a measure of a deviation from ideal behavior. The lower the van ’t Hoff factor, the greater the deviation. As the data in Table … WebJul 1, 2024 · To find the temperature change elevation of a solvent by a solute, use the freezing point depression equation: ΔT = iK f m. where. ΔT = Change in temperature in °C. i = van 't Hoff factor. K f = molal freezing point depression constant or cryoscopic constant in °C kg/mol. m = molality of the solute in mol solute/kg solvent.
Web1.86 degrees Celsius/molal. What is one way to explain the freezing point depression effect? Consider the solute particles as interfering or standing between the solvent particles. With greater space between the solvent particles, intermolecular forces are weaker. WebAug 31, 2024 · Equation 12.5.4 becomes. K = e − ΔrHo / RTeΔrSo / R. Taking the natural log of both sides, we obtain a linear relation between lnK and the standard enthalpies and entropies: lnK = − ΔrHo R 1 T + ΔrSo R. which is known as the van’t Hoff equation. It shows that a plot of lnK vs. 1 / T should be a line with slope − ΔrHo / R and ...
