焓(H)enthalpy- used to quantify the heat flow into or out of a system in a isobaric process
熵(S)entropy- is a measure of the randomness or disorder of a system
And we have the equation that :H=G+TS
(楼主建议你写段原文看看, 我学的教材里面不把焓说成化学反应的驱动力, 而是化学反应的恒压热效应)
s是熵，H是焓，熵在平衡状态下等于热温商，就是S=Q/T，熵和吉布斯自由能的关系是G=H-TS
热力学基本关系是U=Q+W H=U+PV G=H-TS A=U-TS 还有一些微分式可以自己推导``````
