In other words, if we don't have to worry about entropy or volume equilibrium is achieved when energy is at a minimum.
换句话说,如果我们不担心熵,和体积的平衡,那么能量就得是最小的。
Still, the actual equilibrium depends on entropy also, not only on the energy.
而且,实际的平衡依赖于熵,而不仅仅是能量。
And so what I get is the energy of the system at the equilibrium separation is given by minus z plus.
这就是通过减去z+得到得平衡分离时,我得到的能量体系。
There's a balance here between ordinary energy or enthalpy and entropy.
通常所说的能量,或者自由焓和熵之间存在一个平衡。
In the case here, tha t I just illustrated with the little cart going down the valley, would be exactly the same with regular energy, the equilibrium state is one of lowest energy, right.
在现在所考虑的情况下,我刚才所描述的小车沿着山谷下行,结论会像能量判据一样,平衡态是能量最低的态。
So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.
关键在于,这种能量与熵之间的平衡,确定了平衡的条件,在化学中能量涉及键能,而熵和无序有关,即有多少可能的不同组合或者形位,二者的平衡会告诉我们平衡态是什么样子。
