EQUILIBRIUM

1. demonstrate knowledge and understanding that many chemical reactions are reversible and the direction of a reversible reaction can be changed by altering the reaction conditions;

2. demonstrate knowledge and understanding that dynamic equilibrium occurs in a closed system when the rates of forward and reverse reactions are equal and the amounts of reactants and products remain constant;

3. state Le Châtelier's Principle and use it to predict the qualitative effects of changes of temperature, pressure and concentration on the position of equilibrium for a closed homogeneous system;
