Kinetics and Equilibrium
- Why do changes in temperature and concentration affect the rate of a reaction?
- Why do changes in temperature, reactant concentration, and product concentration affect the equilibrium point of a reaction?
Objectives
- Calculate the rate law
- Determine the units for K
- Write an equilibrium expression
- Use the equilibrium to determine which side of the reaction is favored
- Calculate the equilibrium constant or concentrations at equilbrium
- Apply Le Chatelier’s principle to reactions
Unit 5 Packet
Day 1: 2/3How Fast Can it Go? Today we will explore in class how temperature and pressure affect the rate of a reaction and begin to calculate rate laws?
A Kinetics Lab Please watch the following video over kinetics for Monday. There will be a daily quiz. |
Day 2: 2/6The Nuts and Bolts of Kinetics: Today we will discuss what has to happen for a reaction to occur using collision theory. We will reflect on the kinetics lab and discuss how temperature and concentration affect the rate and determine how to show this mathematically.
Solutions to More Kinetics Practice (pp 18_19) Please watch the following video over basic equilibrium for next class. |
Day 3: 2/8Can a reaction go forever? Certain reactions establish equilbrium. Equilibrium is a state when the rate of the forward reaction is equal to the rate of the reverse reaction. To the naked eye it will appear as if nothing is happening. Today we discuss how to write an equilibrium expression, how to solve for equilibrium concentration using RICE tables and what exactly the equilibrium constant tells us.

Day 4: 2/13What Happens When the System is Stressed? Today we will discuss Le Chatelier's Principle which explains what happens to a system at equilibrium when a stress is applied. The most common stresses that can be applied are changes in concentration, temperature, and pressure/volume. Le Chatelier's simply states that to reestablish equilibrium the reaction is going to shift in the direction opposite the stress (need to relieve the stress).
