- In a reversible reaction, the products can react again to form the reactants again.
- As the reactants react, their concentrations fall- so the forward reaction will slow down.
- But as more and more products are made and their concentrations rise, the backward reaction would speed up.
- After a while, the forward reaction will be going at exactly the same rate as the backward one- the system is going at equilibrium.
- At equilibrium, both reactions are still happening, but there's no overall effect (it's at dynamic equilibrium). This means the concentrations of reactants and products have reached a balance and won't change.
- Equilibrium is only reached if the reaction is in a closed system. A closed system is where none of the reactants or products can escape and nothing can get in.
- When a reaction's at equilibrium, it doesn't mean the amounts of reactants and products are equal
- If the equilibrium lies to the right, the concentration of products is greater than that of the reactants.
- If the equilibrium lies to the left, the concentration of reactants is greater than the concentration of the products.
- The position of equilibrium depends on the following conditions (as well as the reaction itself): the temperature, the pressure (this only effects equilibria…
