7.2 Direction of Reversible Reactions
In short
You are expected to understand that the net direction of a reversible reaction depends on the relative rates of the forward and reverse processes. You must know that a net conversion of reactants to products occurs when the forward rate is greater than the reverse rate, and a net conversion of products to reactants occurs when the reverse rate is greater than the forward rate.

What else do you need to know about Direction of Reversible Reactions?
Furthermore, you must recognize that chemical equilibrium is the dynamic state reached when the rates of the forward and reverse reactions become equal.
How is Direction of Reversible Reactions tested on the exam?
Questions may assess the suggested skill of Model Analysis (4.D), requiring you to explain the degree to which a model or representation describes the connection between particulate-level properties (such as reaction rates) and macroscopic properties (such as the net conversion of species). You should be prepared to justify the direction of a reaction or the establishment of equilibrium based on relative reaction rates.
