Conditions and Reversible Reactions. Flashcards
What is the effect of changing conditions in an equalibberian?
- If a system is at equilibrian and a change is made to the conditions:
- The system will respond to counteract the change.
- Le Chateliers Principle.
What happens if we increase the concentration of a system that is in equilberian?
- System will counteract the change.
- System is no longer at equillberian.
- Forward and reverse reactions are not taking place at the same place.
- Concentration of all substances will change until equailberian s reached.
What happens if we increase the concentration of a system that is in equilberian?
- System will counteract any changes made to the conditions of the equiliberian.
- Changing the concentration of the reactants or products:
= System is no longer at equillberian. - Forward and reverse reactions are not taking place at the same place.
- Concentration of all substances will change until equailberian s reached.
What happens when we increase the temperature of a system that is in an equaliberian?
- If we increase the temperature of the system (exothermic reaction), the reaction will shift to the side of the endothermic reaction to reduce the temperature.
How does the change in pressure affect the equliberian?
- Involves gases.
- If we increase the pressure of a reversible reaction at equailberian, the position of the equilbian shifts to the side with the smaller number of molecules.
Reduces the pressure: it will shift with the side with a greater amount of molecules.
If the number of molecules are the same on both sides:
- changing pressure has no effect.
