所以如果一个反应 比如说 A加上B 生成C 那么反应的焓变...
So if you have a reaction, let's say A plus B yields C and our change in enthalpy so our enthalpy in this state minus the change in the enthalpy in that state so
因为焓变... 如果系统恒压... 焓变就等于系统吸收的热量
Because change in enthalpy, when we're dealing with a constant pressure system, is heat added to the system.
反应的焓变是正的
Your change in enthalpy is positive.
我们可以从焓开始看
So we could start with enthalpy.
而反应吸收的能量 就是焓变
The amount of energy you absorb is your change in enthalpy.
看起来 用焓变来判断 是个不错的方法
like this change in enthalpy is a good candidate.
而且我们知道 因为这次的焓变小于0
And we know that, because this was the change in enthalpy was
那么如果 焓是负的 熵是正的 反应释放能量
And then if we go to the negative enthalpy, positive entropy, so we're releasing energy, so this is negative, and our entropy is increasing our entropy, we're getting more disordered then this becomes a negative as well.
如果这项正数够大 它就会抵消掉所有的负焓
If this is positive enough, it will overwhelm any negative enthalpy.
所以只有焓的话 不能判断反应是否能自发进行
So maybe enthalpy by itself wouldn't completely describe what's going to happen.
如果温度很低 分子可能飘到一起 然后表达式里 焓的部分
When temperature is low, maybe they'll drift close to each other, and then the enthalpy part of the equation will matter more.
现在我们假设反应焓变小于0 我们看出来它是个放热反应
let's say our change in enthalpy is less than 0, we know that this is exothermic.
所以从焓变上看 它们没有理由 向左反应 或者说 在能量层面上有了向右反应的
So there's no even kind of enthalpic reason for them to move in this direction, or you know, kind of a energy reason for them to move in this direction.
