目前,仍然有许多人使用体积摩尔浓度报道溶液中的化学反应速率和化学平衡常数,并且用体积摩尔浓度讨论实验结果,这实在是件憾事。体积摩尔浓度即反应物T在1升溶液中的摩尔数,并用C_J来表示。这种浓度表示法在分析化学中使用起来是很方便的。但是,只要我们考虑到溶液的体积与温度和压力有关,那么,使用体积摩尔浓度就很不方便的了。 At present, there are still many people who report chemical reaction rates and chemical equilibrium constants in solution by volume and molar concentration, and discuss the experimental results in terms of molarity. The molarity of the moles of reactant T in 1 liter of solution is expressed in terms of CJ. This concentration notation is very convenient for use in analytical chemistry. However, as long as we consider that the volume of a solution is related to temperature and pressure, it is inconvenient to use the molarity of the solution.
