*** WHAT'S COVERED ***
1. Reversible Reactions
* The difference between one-way and reversible chemical reactions.
* Understanding the forward and backward reactions indicated by the double arrow symbol.
2. Dynamic Equilibrium
* How the rates of the forward and backward reactions lead to a state of equilibrium.
* The definition of dynamic equilibrium: when the rates of the forward and backward reactions are equal.
* Why the concentrations of reactants and products remain constant at equilibrium.
* The necessity of a closed system for equilibrium to be established.
3. The Position of Equilibrium
* What it means for the position of equilibrium to lie to the left or to the right.
* How the position of equilibrium relates to the relative concentrations of reactants and products.
* An overview of how changing conditions (like temperature) can shift the position of equilibrium.
4. Energy Changes in Reversible Reactions
* The principle that if the forward reaction is endothermic, the backward reaction is exothermic, and vice-versa.
* An example using the thermal decomposition of hydrated copper sulfate.
