ΔE,ΔH,q,w,ΔU,怎么好像ΔE,ΔU都是内能的意思.有什么区别?
which of the following statement is CORRECT
a.if a reaction occurs at constant pressure,w=ΔE
b.if a reaction occurs at constant pressure,q=ΔH
c.if a reaction occurs at constant pressure,q=ΔE
d.if a reaction occurs at constant volume,ΔE>ΔH
e.if a reaction occurs at constant volume,w=ΔE
应该选什么?
请问ΔE和ΔU有什么区别?

选择B.
ΔE,ΔH,q,w,ΔU的意思分别为:
能量变化量
焓变
热量
功
热力学能变化量
△U是指系统内能的增量,ΔE则是总能
