lavancement dune reaction ,note x,est la 
quantite qui sest transformee a un instant donne.

x:avancement
xf: avancement final(quantite de matiere transformer
 quand la reaction sarrete)
xmax:avancement max,plus grande quantite de matiere qui peut 
etre transformer si la  reraction est totale 

---------------------------------
|aA   +     bB  ->  cC  +   dD
|--------------------------------
|nA      |nB     |   0  |   0
|--------------------------------
|nA-a*xf |nB-b*xf|  C*xf|  D*xf
---------------------------------

une reaction est totale quand o moins un des deux
 reactif est epuise a letat final

non totale quand aucun des reactif est epuisée totalment 

pour calculer xmax on fait 2 hypothése 
xmax est la plus petit valeur des deux hypothese 

1/ n0(A)-axmax=0 
2/no(B)-bxmax=0

le reactif limitant est egal
 a 0 a letat final 
 
 melange stoechiometique si les quantite de matiere 
 initial des reactif sont dans les meme proportion 

 n0(A)/a=n0(B)/b
