1. What is the maximum number of homogeneous phases that can exist at equilibrium for a system involving
- a liquid phase and a vapor phase, each of which contains ammonia and water.
- liquid mercury, liquid water, and a vapor phase of mercury and water.
- liquid acetone and a vapor phase of acetone and N2.
2. Develop the phase rule for chemically reacting systems.
3. Determine the number of degrees of freedom for the gas phase reaction:
