Question 1

Free energies are state properties of a system

Answer 1

T

Question 2

The Gibbs free energy of a system is a portion of the energy in the system available for conversion to work

Answer 2

F

Question 3

For a reversible phase change at constant T&P, there is no change in Gibbs free energy (ie ΔG=0)

Answer 3

T

Question 4

When a closed system approaches to equilibrium at const T&P, the free energies G and A decrease until material equilibrium is reached.

Answer 4

F…G decreases but not A

Question 5

The beaker is to be filled with a binary water-ethanol solution at constant T&P. The chemical potential of water in the beaker will remain the same as the beaker is gradually filled with the solution

Answer 5

T

Question 6

Chemical potential of 1 mol of water vapor at (100 °C, 1 atm) is the same as the chemical potential of 10 mol of liquid water at the same T and P

Answer 6

T
