EQUILIBRIUM: Concepts and Applications (2 Programs)
What is chemical equilibrium, and how does it work? This down-to-earth two-part series uses real-world examples and analogies to offer an in-depth look at both the concepts and applications of equilibrium. Sample problems are provided.
The series consists of two programs 21-24 minutes each:
THE CONCEPTS OF EQUILIBRIUM
Starting with a definition of reversible reactions, this program covers the basic concepts of chemical equilibrium and the equilibrium law. The concept of equilibrium is illustrated by comparison to the movement of cars in and out of a parking lot, the motion of a person walking the opposite way on a moving walkway, and the movement of people on and off paddleboats. The video concludes by considering what an equilibrium constant indicates about a reaction in terms of the relative quantities of reactants and products present at equilibrium. Carbon monoxide in the bloodstream is used to illustrate that point.
APPLYING THE CONCEPTS OF EQUILIBRIUM
This program begins with an overview of the basic concepts of chemical equilibrium: reversible reactions, Le Châtelier’s principle, the equilibrium law, and the calculation of K. It then analyzes how changing conditions other than temperature leads to a temporary shift in the position of equilibrium and how reactions spontaneously adjust to maintain the value of K for any given temperature. Changes in K when increasing and decreasing the temperature of exothermic and endothermic reactions are examined as well, and the concept of equilibrium as it relates to the industrial manufacture of sulfuric acid is highlighted.
