enthalpy function 定义函数为焓函数。其中及分别为温度TK及0K时的标准焓。 物理化学手册中给出不同温度TK时单质和化合物的焓函数。 利用这些数据计算化合物的标准生成焓,用焓函数的优点是免去使用热容的经验式。
并从色谱热力学函数分析了保留指数随温度变化规律的主要原因是由于在色谱分离过程中不同的熵变和焓变所造成的。
The changing law of retention index with temperature from chromatographic thermal function resulted from the variation of the different entropy and enthalpy during the chromatographic separation.
从热力学第二定理出发,利用外微分构造了熵、焓以及吉布斯函数的表达式。
Expressions of entropy, enthalpy and Gibbs function are formulated by exterior differential derived from second law of thermodynamics.
求出了标准摩尔吸附吉布斯函数、标准摩尔吸附熵和标准摩尔吸附焓。
Standard molar adsorption Gibbs function, standard molar adsorption entropy and standard molar adsorption enthalpy are derived.
It's a state function. If we know the enthalpy of the products minus the enthalpy of the reactants, right. It's a state function.
如果我们知道生成物的焓减,去反应物的焓的值,它是个态函数,原则上我们可以做到。
It turns out we can express all these functions in terms of G, G we wouldn't need to choose G, but it's a very useful function to choose.
最终我们能把所有的这些函数,用自由焓G表示出来,我们没有必要选择,但是这个选择很有用。
