1问题的引出我们知道，在恒温恒压条件下，一切自发过程都是向自由能G减少的方向进行，而且de越小，过程进行的趋势就越大。那么对于金属在空气中被氧化趋势的大小同样也可根据凸C的大小来判断，这是毫无疑问的。我们先看下面一道习题：试利用标准生成自由能数据来判断金属Mg、 1 The problem leads to We know that under constant temperature and pressure conditions, all the spontaneous processes are to reduce the free energy G direction, and the smaller the de, the greater the trend of the process. So for the metal in the air is oxidized the size of the same trend can also be judged according to the size of convex C, there is no doubt. Let us first look at the following exercise: Try to use the standard data to generate free energy to determine the metal Mg,
