the energy gap of 3 kilocalories per mole between the two extreme forms translates into a population difference:at any given instant at room temperature there will be on average 100 ethane molecules in the staggered form for each one in the eclipsed form.
我也是因为不知道后面那句话的意思才来问的啊。。。
追答额,你知道staggered form和eclipsed form是什么意思么?
追问staggered form这个是交叉式,eclipsed form这个是重叠式
追答找了一下原文,我觉得你看下面那个图就知道了:同样的物质如果是多了3千焦每摩尔就是重叠式,少了就是交叉式……
我说怎么看原文看了半天也没明白到底哪个能量多哪个能量少…………
