etat final = etat equilibre

aA+bB<=>cC+dD
-> sens direct
<- sens indirect
<=> se lit transformation non totale

T=xf/xmax
Si T=1 :transformation totale 
et xf=xmax
Si T<1 :non totale et xf<xmax

Pour determiner le taux davancement
final de la reaction... :
-tableau davancement
-calcul de xf (voir produits)
-calcul de xmax(calcul du reactif
limitant 
xmax1= (n1(reactif)/nbr stoech)
xmax2= (n2(reactif)/nbr stoech)
xmax le plus grand est le xmax
du reactif limitant
-calcul de T

Qr=[C]**c*[D]**d/[A]**a*[B]**b
Si esp chim est solide solvant 
ou h20 alors mettre 1

mais aussi : ([A]/C**0)**a
rajouter apres chaque []i/eq/f

K depend que de la temperature,
pas des conditions initiales
K=Qr
Qr,i<K:sens direct
Qr,i=K:etat d eq
Qr,i>:sens indirect
trans chim consideree comme tot
si K>10**4
