TraeFabe Questions:( pt each) Plese indicate fF ach sacement In the kinetic molecular theory of gases, molecular collisions can be inelastic. The van der Waals b constant is large for large molecules. The Boyle temperature is the temperature at which _- op av _ At the critical point for a gas, A process with AA 0 (at constant temperature and volume) will be spontaneous. For an adiabatic change, q--w. The chemical potential of a substance is increased by the introduction of an impurity The most thermodynamically stable phase has the highest chemical potential. The equilibrium constant for a reaction is independent of temperature The equilibrium constant of a reaction is independent of pressure

Explanation / Answer

- False as the Kinetic Molecular Theory of gases states that gas particles are in constant motion and exhibit perfectly elastic collisions.

- True as the Van der waals constant b is larger for larger molecules as the surface area increases.

- True as the temperature for which the second virial coefficient becomes zero thus at Boyle temperature (delta Z/ delta p)T = 0

- True as the first and second partial derivatives of the pressure p with respect to the volume V are both zero, with the partial derivatives evaluated at constant temperature T in a critical point.

- False as the proces in which G < 0 is spontaneous

- False For an adiabatic change , q = 0

- True as the in the chemical potential rate of change of a free energy of a thermodynamic system with respect to the change in the number of molecules or atoms of the species that are added to the system.

- True as in the fundamental equation of thermodynamics  all intensive quantities are holds for both reversible and irreversible processes.

- False as equilibrium constant depends on temperature (log Keq = (-delta Go/ RT)

- True as the equilibrium constant of areaction is independent of pressure ( (log Keq = (-delta Go/ RT)
