Hoff equation
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, … Consider the system at the point when it has reached equilibrium. The condition for this is that the chemical potential of the solvent (since only it is free to flow toward equilibrium) on both sides of the membrane is equal. The compartment containing the pure solvent has a chemical potential of , where is the pressure. On the other side, in the compartment containing the solute, the chemical potential of the solvent depends on the mole fraction of the solvent, . Besides, this compartment c…

The Van 't Hoff equation relates the change in the equilibrium constant, Keq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, ΔrH , for the process. It was proposed by Dutch chemist Jacobus Henricus van 't Hoff in 1884 in his book Études de Dynamique chimique … Se mer Summary and Uses The standard pressure, $${\displaystyle P^{0}}$$, is used to define the reference state for the Van 't Hoff equation, which is where ln denotes natural logarithm, In practice, the … Se mer For a reversible reaction, the equilibrium constant can be measured at a variety of temperatures. This data can be plotted on a graph with ln Keq … Se mer • Clausius–Clapeyron relation • Van 't Hoff factor (i) • Gibbs–Helmholtz equation Se mer Van 't Hoff analysis In biological research, the Van 't Hoff plot is also called Van 't Hoff analysis.
