Thermodynamics And Phase Equilibrium And Chemical Equilibrium

Front 1

Define the internal energy, enthalpy and entropy

Back 1

Energy: Sum of all the energy at the microscopic level (translational, rotational, vibrational, nuclear)

Enthalpy: Energy + Work on system

i.e. DeltaH = DeltaU + PDeltaV

Entropy: Measure of disorder

i.e. DeltaS(sys) = Delta

Front 2

Classify a process as spontaneous or not in terms of the total entropy change of the universe

Back 2

Second law of thermodynamics: Change in entropy in the universe must increase for a spontaneous reaction

Front 3

Explain phase stability in terms of the Gibbs energy

Back 3

O

Front 4

Use a binary phase diagram to determine the following for a given overall composition and temperature: what phases are present, the composition of each phase, the amount of each phase

Back 4

O

Front 5

Contrast the amount of a phase in a system with the composition of that phase
