Enthalpie Standard de réaction : Somme Vi*ΔfH°
ΔrH°= somme Δf + produit - reac
ΔrS°= pareil avec S
Enthalpie de Réaction ΔrH=ΔrU°+RT*Somme Vi gaz
ΔH=Qp
Attention j.mol et pas kj
pour Vi + produit - reactif
ΔrH°(T)=ΔrH(Tref)+int tref a T somme ViCpidT
ΔrG°=ΔrH°-TΔrS°i=-RTlnKp
dlnK/dT=ΔrH°/RT^2 -> lnKpT=lnKpTref+int droite
avec lnkpTref=ΔG/-RT

calculer Kp :
  tableau avancement 
  n + n + 0 Tot 2n
  n-ViE + n-ViE + ViE Tot 2n-Vie
Kp = Fin prod / Fin reac 1 * Fin reac 2
  Ppartielle = Fin / Tot * Pt
  On prend celle prod = Pression donnée on résout n 
  puis déduire expression Kp
  
Aéotrope composition 1 = 2

titre massique = mparticulier/mtot
