If I charged the reactor in this manner, and of course I'm assuming 100% completion of the reaction which we know is overly optimistic.

如果我们这样来考虑这个反应的前提，就是我们假设,反应完全进行,我们知道这有些过于乐观了。

And then, of course, not just whether the reaction will occur but, how fast it occurs is really important.

当然，我们不光要研究一个反应会不会发生,反应速率多块也是很重要的研究问题。

We want to have that definition clear because in fact we're going to, we might want tabulate heats of reaction, right, and of course want to know what the conditions are for the tabulated values apply. And we're going to want to calculate them from other quantities and again, we're going to need to know each case what are the relevant conditions?

我们想要明确这个定义,因为实际上我们会想把,反应热制成表格，当然我们会,想知道表中的数据在什么样的,条件下是有效的，我们会,想要从其他的量中算出它们,再一次，我们需要知道,每种情形下相关的条件是什么？

Of course, they're all sorts of conditions under which a reaction could be wrong in the lab or outdoors or however, right. But this is the way we're going to define delta H of reaction.

当然，在实验室或室外,之类的环境中，在这些条件下,反应可能出错，但这是我们,要定义反应的△H的方法。
