OK, now I have this derivative of the Gibbs free energy divided by the temperature. 现在要进行微分,对除以温度之后的吉布斯自由能。
And then we can also write this in terms of the Gibbs free energy for the reaction. 然后我们可以用反应的,吉布斯自由能把它写出来。
The Gibbs free energy. Notice, we could also write, let's rewrite that. 吉布斯自由能,注意,我们还可以这样写,重写一下。
The Gibbs free energy per mole of A in the liquid phase. 液相中的化学势就是,液相中每摩尔A的吉布斯自由能。
Well, we know how Kp depends on temperature, through the Gibbs free energy of the reaction. 好我们知道Kp依赖于温度,通过反应的。
It's the state that has the lowest Gibbs free energy. 它具有最小的吉布斯自由能。
In addition, the activation free energy △ G for the ET reaction has been evaluated. 本文还计算了该电子转移反应的活化自由能△G。
Helmholtz free energy? Enthalpy? Which one? 亥姆霍兹自由能?自由焓?哪一个?
Per mole, which is just the Gibbs free energy of vaporization. 每摩尔吉布斯自由能,就是汽化的吉布斯自由能。
What is free energy? 什么是自由能呢?
For the Gibbs free energy it was the pressure and the temperature, the number of particles. 对吉布斯自由能是压强,温度和粒子数。
And so that led us to the definitions of other energy quantities, the Helmholtz and Gibbs free energy. 这就要求我们定义,其他的和能量相似的物理量,亥姆赫兹和吉布斯自由能。
The free energy increases monotonically with increasing radius. 自由能随半径的增大而单调地增加。
So a pretty simple form for the Helmholtz free energy. 亥姆霍兹自由能的一个比较简单的形式。
Free Energy, Enthalpy, and Entropy. 自由能,熵,以及焓。
More free energy devices will become available, particularly for powering our homes and transport systems. 更多免费能源设备加入,特别是为我们的家园供电和运输系统。
Effect and Simulation of Coupled Heat and Mass Transfer on Adsorption and Pressure Swing Adsorption The studies both on the enthalpy and on the free energy of adsorption manifest a physisorption process. 吸附与变压吸附过程传热传质耦合影响及其模拟研究对吸附焓变和自由能变的讨论同时表明树脂对对甲苯胺的吸附为多层物理吸附过程。
We learned that the pressure dependence of the Gibbs free energy gives you the pressure dependence for the chemical potential. 我们还知道吉布斯自由能,对压强的依赖关系决定了,化学势对压强的依赖关系。
Minimum free energy method is adopted to calculate gas components with the increasing of AN. 采用最小自由能法理论计算了硝酸铵发射药燃气组成随硝酸铵的变化。
And it relates the temperature change in the Gibbs free energy with the enthalpy change. 这个方程把吉布斯自由能中的温度变化,和焓的变化联系起来。
What that suggests is that actually the simplest and most natural connection between Q and macroscopic thermodynamics is to the Helmholtz free energy. 这暗示我们,最简单最自然的联系,在Q和宏观热力学两之间,是和亥姆霍兹自由能的联系。
This quantity is positive with respect to the free energy of the bulk condensed phase. 对于主体凝结相的自由能来说,这个量是正的。
In other words, there's a free energy per molecule. 换句话说,存在每个分子的自由能。
Now, the chemical potential, as we saw, was the Gibbs free energy. 现在,化学势,就像我们看到的,等于吉布斯自由能。
So we can replace this with the change in Gibbs free energy from going from gas to liquid. 所以这一项我们可以替代它,用从气相到液相变化的吉布斯自由能。
