Study Notes
Equilibrium Constant
- An equilibrium constant is found by dividing the product of the products by the product of the reactants.
Reaction Direction
- If a reaction mostly gives products, then K is large.
K Expression
- For a given reaction, the correct K expression is determined by the reaction's equation.
Reaching Equilibrium
- If a reaction is started with all products and no reactants, the amount of reactants will increase as the reaction reaches equilibrium.
