Changing the position of equilibrium:
Le Chatelier's principle: If a constraint is imposed on a system at equilibrium, then the system will respond in such a way as to counteract the effect of that constraint.
- Le Chatelier's principle predicts that if a reactant's concentration in a system is increased, the system will move to the right in order to decrease the concentration of that reactant.
- If the reactant's concentration is decreased, the system will move to the left in order to replace the reactant.
- This works with the product as well.
- Changing the concentrations of reactants and products has no effect on the rate constants of the forward or reverse reactions. Therefore, it has no effect on the equilibrium constant.
- The pressure in a system depends on the number of gas molecules in the system.
- Le chatelier's principle therefore predicts that if the pressure of the system is increased, the system will move towards the side which has fewer gas moles.
- If the pressure of the system is decreased, the system will move towards the side which has more…
