Final answer:
The factors of H-W equilibrium include increased temperature, addition of H2, and decreased pressure. To predict the direction of shift for each stress, consider the effect of each factor on the equilibrium.
Step-by-step explanation:
The factors that can affect the equilibrium of a chemical reaction, known as the Haber-Weiss equilibrium, include:
- Increased temperature: Heating the system will cause the equilibrium to shift in the direction that consumes heat, typically the endothermic reaction.
- Addition of H2: Increasing the concentration of H2 will shift the equilibrium towards the products, following Le Chatelier's principle.
- Decreased pressure: Reducing the pressure will favor the side of the reaction with more moles of gas.
To predict the direction of shift for each stress, you should consider the effect of each factor on the equilibrium. For example, increased temperature will shift the equilibrium towards the endothermic reaction, while decreased pressure will favor the side with more moles of gas.
