AP Chemistry 7.8 Representations of Equilibrium Study Notes New syllabus
AP Chemistry 7.8 Representations of Equilibrium Study Notes – AP Chemistry – per latest AP Chemistry Syllabus.
LEARNING OBJECTIVE
Represent a system undergoing a reversible reaction with a particulate model.
Key Concepts:
- Calculating the Equilibrium Constant
- Magnitude of the Equilibrium Constant
- Manipulating the Equilibrium Constant
7.8.A.1 Q vs. K: Predicting Reaction Direction and Equilibrium:
1. Particulate Representations:
Particulate representations show how reactant and product particles are arranged during a reaction.
– Reactants: Show molecules or ions before the reaction.
– Products: Are the new resulting molecules or ions.
– At equilibrium: Reactants and products will always be in the same ratio, and forward and reverse reactions occur at the same rate.
2. Equilibrium and
The equilibrium constant (K) is a ratio of products to reactants at equilibrium:
– High ( K ) (K > 1): More products.
– Low ( K ) (K < 1): More reactants.
The particle distribution at equilibrium to ( K ), showing the ratio of reactants and products.
