Study Notes
- Dynamic equilibrium involves reversible reactions where forward and backward reactions occur at the same rate simultaneously within a closed environment.
Reversible Reactions
- The production of ammonia (N2(g) + 3H2(g) ⇌ 2NH3(g)), known as the Haber process, is a reversible reaction.
- The reaction between hydrated copper sulfate and water to form anhydrous copper sulfate is reversible.
Le Chatelier's Principle
- If the conditions of a system at equilibrium change, the system will react to counteract that change.
- For example, if heat energy increases, the rate of the endothermic reaction will increase.
The Haber Process
- The Haber process produces ammonia from hydrogen and nitrogen.
- The production of ammonia is exothermic, while the reverse reaction is endothermic.
- Increasing pressure in the Haber process leads to more ammonia production, as it results in fewer gas molecules.
- Fewer gas molecules mean less pressure is exerted, counteracting the initial pressure increase.
