稳定性弄清平衡与稳定之间的区别是重要的.平衡是表述引起反应或转化的动力等于零时的条件.这个动力与附加于物系上的条件有关.如果物系的体积和熵不变,则实现反应的动力改变着物系的内能;P和T值不变时,动力改变着自由能,等等.若物系处于平衡,将不产生任何变化.但平衡不一定都是稳定的.比如说,山顶上的一块圆石头,最初是不动的(处于平衡),但只需很小的推力,就足以使它滚到山下,因此说石头是处于不稳定的平衡.目前还没有一个稳定性的普遍准则,能够概括物系中能发生的所有可能的转化.物系相对于一个反应而言可能是稳定的,但相对于另一反应则不稳定.常温下,石英对于任何多
Stability It is important to understand the difference between equilibrium and stability. Equilibrium is a condition that states that the power that causes the reaction or transformation to be equal to zero depends on the conditions attached to the system.If the volume and entropy of the system remain unchanged , Then the motivation to effect the reaction changes the internal energy of the species; when the P and T values are constant, the motive force changes the free energy, etc. If the species is in equilibrium, there will be no change, but the balance is not always stable For example, a round stone on the top of a mountain is initially not moving (in balance), but only a small lift is enough to get it down the mountain, so that the stone is in an unstable equilibrium. A general rule of stability that summarizes all possible transformations that can take place in an object system that may be stable with respect to one reaction but unstable with respect to the other.In general,
