Mixture thermodynamics Flashcards
1
Q
Define mixture
A
System in which all components have similar mole fractions
2
Q
Define solution
A
One of components is in large excess => component in excess is the solvent, remaining components are solutes
3
Q
Describe the mixing process
A
Two pure components are mixed at same temp and pressure so final pressure is the same
4
Q
Describe the phase equilibrium of binary mixtures
A
Two phases at the same pressure and temperature are in equilibrium when the chemical potential of each species is the same in both phases.
5
Q
Describe an ideal mixture
A
No change in total volume on mixing => total volume equal to sum of components
=> molecular size and interactions of each component of the mixture are the same
6
Q
What does internal energy depend on?
A
Only temperature
