Thermodynamics Final Formulas

Activity Coefficient

gamma is activity coef

a is activity

X is molar fraction. A/(A+B).

represents how far a solution component is from ideal.

Activity Constant

products/reactants.

Classius Clapeyron

Compressibility Factor

Definition of Activity

Expansion Coefficient

Gibbs-Helmholtz equation

Gibbs Phase Rule

LEARN

Henry’s Law, Raoult’s Law

Raoult’s is just as composition approaches 1, activity approaches just Xa.

Isothermal Compressibility

Nurst Equation

Single Particle Partition Function

Van Der Waals EOS

Regular Solution Model

adiabatic, reversible, ideal gas, path?

PV^gamma = cst. When no heats exchanged, work comes from internally, so temperature drops when exerting work. vice versa. gamma = Cv/Cp, >1.

Entropy using boltzmann?

Gibbs Duhem

Partial Molar Enthalpy

Chemical Potential

also = to activity

Standard Cell Potential

Uppercase vs lowercase (H vs h, V vs v?)

Uppercase is extensive, lowercase is molar specific.

Avg partial molar volume of water?

18 grams per mole

Aqueus Activity for Dissolving?

Activity referenced to molal of material you’re dissolving = gamma^(sum of stoich A+B ) * molality of component A]^(stoich A) * molality of component B^(stoich B)

Cell types?

Galvanic produces electricity, electrolysis uses energy.

3 galvanics:

daniel/displacement, formation, and concentration…
