aA + bB <-> cC + dD
Xf<Xmax
Vdis(A)=-d[A]/dt
Vapp(A)= d[A]/dt
Xf si Vapp=Vdis
Avancement final T= Xf /Xmax
Si T=1 transfo totale sinon reaction limitee et tranfo non totale
Qr= ([C]/C°)**c  *  ([D]/C°)**d  /  ([C*A]/C°)**a  *  ([B]/C°)**b (mol/L)
Qr eq= K
Qr<K sens direct de l eq
Qr>K sens indirect de l eq
Ox + n e- = Red
Role pont salin= electroneutralite +  continuite electrique du circuit
Qmax = n(e-)max * Na * e
dt= Qmax/1
reducteurs= H2
oxydants= O2 ClO- Cl2

A=lambda*N
Lambda= constante S-1
N= nombre de noyaux radioactifs
A=-dN/dt=lambda*N
N(t)=N0 exp (-lambda*t)
A(t)=N*A0 exp (-lambda*t)
t1/2=ln2/lambda
t=(-t1/2/ln2)*ln(N(t)/N0)
