What is the microcanonical ensmble?
An isolated system
What does the 2nd law state?
dS≥0 for all processes in an isolated system
When is a process reversible?
When it is performed quasitatically
When it involves on dissipation
How does entropy change for general processes?
S increases until dS=0 at maximum
What is the probability of microstates at maximum entropy?
Equally probable

T and V

dH≤0 for fixed S and p
How the Gibbs free energy change for the canonical ensemble?
dG≤0 for fixed T and p
what is the result of minimising the Helmholz free energy?
Get the Boltzmann distribution
Which is the definition of the canonical ensemble
