標題[問題] Gibbs-Duhem equation
時間Fri Nov 22 11:58:42 2013
課本上的
The Gibbs Duhem equation
G=ΣniGi → dG=Σ(nidui+uidni)
因為dG=-SdT+Vdp+Σuidni
因此,Σnidui=-SdT+Vdp=0 (在定溫定壓下)
今天在書上看到一個題目
Q:what is the general form of the Gibbs-Duhem equation for the any molar
thermodynamic property M in a homogemous phase?
ANS:ΣxidMi=0
有點看不懂題目指的M是代表甚麼意思???
