Week 2 Chemical Potential Flashcards
what are the three chemical potential differential eqn
μ = dG/dN = dF/dN = dE/dN
what is gibbs energy chemical potential
G = ΣμiNi
what is the partial pressure eqn
Pi = (Ni/N)P
what is true of the Gibbs free energy at eqm
it is at a minimum
what is the eqm constant eqn
Kp = exp[-gr/RT0] = Q
how do you know if a reaction favours the products or reactants
if Q < Kp more product
if Q > Kp more reactants
what is the relation between microstates and macrostates
Properties of a macrostate are averaged over many microstates
what is the macrostate eqn
= ΣpiXi
describe the 3 ensembles
microcanonical ensemble - real system is isolated
canonical ensemble - real system is in contact with heat
grand canonical ensemble - real system exchanges heat and particles
what is the general binomial coefficient equation
N! / n!(N-n)!
