Nettet9. mai 2024 · Osmotic pressure is expressed by the formula: Π = iMRT. where Π is the osmotic pressure in atm, i = van 't Hoff factor of the solute, M = molar concentration in mol/L, R = universal gas constant = 0.08206 L·atm/mol·K, and T = absolute temperature in Kelvin. Step 1: Determine the van 't Hoff factor. Since glucose does not dissociate into ... Nettet31. aug. 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 ...

12.5: The Van
NettetThe van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression.The van 't Hoff factor is the ratio between the actual concentration of … NettetIn the first formula, we calculate the Van’t Hoff factor by using the colligative property. In the second formula, we know that particles with colligative properties have an abnormal molar mass. So, the Van’t Hoff factor can be calculated by taking the values of the calculated molar mass and the experimentally observed molar mass.
