Chapter 18: Chemical Equilibrium

Introduction

Chemical Equilibrium – interactive animations of equilibrium reaction systems.

(Main Idea: In equilibrium, the concentrations of reactants and products remain constant.)

 

Chemical Equilibrium – interactive experiment where you control the number of atoms, the temperature, the volume, and the bonding forces at work.  Watch the system reach
equilibrium, and graph the results.

(Main Idea: In equilibrium, the concentrations of reactants and products remain constant.)

Equilibrium Constants

Calculating Equilibrium Constants – tutorial on calculating equilibrium constant K based on what you know of the equilibrium system.

(Main Idea: In equilibrium, the concentrations of reactants and products remain constant.)

Shifting Equilibrium

Chemical Equilibrium – discussion of equilibrium and Le Chatelier’s principle for shifts in equilibrium systems.

(Main Idea: Equilibrium shifts to relieve stress on the system.)

Equilibrium Changes – video explaining the changes to equilibrium systems in response to changes in concentration, volume, or temperature.

(Main Idea: Equilibrium shifts to relieve stress on the system.)

Reversible Reactions

Reversible Reactions – interactive activity; watch reversible reactions in a controlled chamber, as you control the barrier heights, temperature, and quantities of molecules ‘A’ and ‘B’.

(Main Idea: All reactions are reversible under certain conditions.)
