WebMay 28, 2024 · The van 't Hoff equation applies for reactions at constant T and p. This means that, typically, as the reaction takes place, V will not be constant (unless the molar volumes of the reactants and products are identical). And since a reaction is taking place, the composition will not be constant either. – theorist May 28, 2024 at 5:32
