So now we have a constant volume reversible temperature change.
所以现在我们有一个,等体,可逆的温度变化。
How many moles of gas are there in each case, in reactants and products? If that changes, of course you know that the pressure in there is going to change at constant volume if the amount of gas in there is changing.
在反应物和生成物中,各有多少摩尔的气体?,如果它发生了变化,当然在等体条件下,如果气体的总量,发生了变化,压强也会发生变化。
We've got two cases where each one of those things now is isoelectric with neon.
这里我们有两个例子,现在是氖的等电子体。
And it's still adiabatic, but now it's constant volume. And it's also reversal right.
它仍然是绝热的,但现在是,在等体条件下,它也是可逆的。
Could be done, but easier is to just do the whole thing at constant volume, right, and just run the reaction that way and redo the calculation to be a constant volume rather than constant pressure calorimeter, right.
可以进行测量,但是如果在体积恒定的条件下,做这些会容易得多,还是这样进行反应,但是在等体而不是恒压条件下重新计算。
And so this is a constant volume path then.
因此这是个等体过程。
Well, this is isoelectronic with helium, right, and so is this, isoelectronic with helium.
而且这是He的等电子体,对吧,这就是He的等电子体。
And that in the case of constant volume, U in this case that's my delta u, and then I'll H add my little delta n term to get delta H.
这是在等体情形下,此时的到的是Δ,然后我可以加上Δn的项来得到Δ
