Questions

$(30$ points$)$ Consider the free energy change during a process of changing composition in a mixture according to the following equation: $G=G^o+RTlnQ$

a$.$ How do we understand the spontaniety of this mixing process?

b$.$ How do we calculate the standard free energy change $G^o$ as a function of temperature for the system?

c$.$ Explain how the standard state for mixtures is different than the standard state for pure systems

d$.$ How does Ellingham diagram help us in finding the equilibrium parameters of $K,P_{O2}^{\text{e}\text{q}\text{m}}$

e$.$ What is the meaning of $Q?$

f$.$ How do spontaniety and equilibrium depend on the value of $\frac{Q}{K}?$
