Sequence 1

Question 1

Molalité

Answer 1

nslt Donc mol/kg
mslv

Question 2

Fraction molaire /% molaire

Answer 2

Xslt=nslt Donc pas de unité
(nslt + nslv)

Question 3

Masse volumique

Answer 3

p=m Donc g/ml
V

Question 4

Pourcentage volumique

Answer 4

%v/v=vslt x 100 Donc pas unité
vsln

Question 5

ppmv et ppm

Answer 5

vslt x 10 exp6
vsln

mslt x 10 exp6
msln

Question 6

ppbv et ppb

Answer 6

vslt x 10 exp9
vsln

mslt x 10 exp9
msln

Question 7

% massique

Answer 7

%m/m= mslt x 100
msln

Question 8

Delta g

Answer 8

Deltag=delta h sys- T deltaSsys

Question 9

Delta s univers

Answer 9

Delta s univers=delta s sys +delta s ext

Delta s ext=-deltaHrn/T

Question 10

Pression vapeur

Answer 10

Psln=xslv x p0slv

Xslv =nslv/(i nslt + nslv)

Question 11

Pression osmotique

Answer 11

Pi=i crt

Question 12

i si elect fort ou faible

Answer 12

Fort i = 1+a(p-1)
Faible i = 1+ %diss

Question 13

Somme de x

Answer 13

1

Question 14

Delta hrn =-Delta hres

Question 15

Delta h

Answer 15

Delta h = delta hslt +delta h hyd

Delta h hyd=delta h slv +delta h mélange Delta h hyd est négative (exo)

Answer 16

Dispersion
Dipôle dipôle
Dipôle induit
Pont h
Ion dipole

Question 17

Delta h solution vs entropie

Answer 17

Neg entropie plus forte
