In the biochemical reactions that are taking place in your body, there is equilibrium between a whole myriad of reactants and products, and thank heavens that gets maintained.

在我们身体内进行的,生物化学反应中，大量的反应物和产物,也是处于平衡状态，谢天谢地实际情况就是这样。

So, then we go to thermodynamics and chemical equilibrium, and this is really about chemical reactions -- weather a reaction will go, will it be spontaneous, if there an equilibrium, what direction will the reaction be shifted in.

然后我们要讲到热力学和化学平衡,这都和化学反应有关，一个反应是否能发生,是不是能自发反应，如果存在化学平衡，它会朝什么方向移动。
