- Write the equation for $K_{eq}$ in terms of temperature.
- Is $K_{eq}$ a function of $T$, $P$, or both?
- In the $K_{eq}$ equation, is the Gibbs energy at the reference temperature or the system temperature? What about pressure?
- If the equilibrium constant $K_{eq}$ is not a function of pressure, can the composition still depend on pressure?
- Write the relation between $K_{eq}$ and the species partial pressures.
- Define partial pressure of a species in terms of mole fraction.
- For a reaction $aA + bB \leftrightarrow cC$, write the moles of each species in terms of some extent of reaction $\xi$.
- Outline all the steps for computation of the equilibrium composition for the reaction in the previous question.
- How many equations and unknowns would you have if there were two reactions?
- Outline the solution in that case.
