S.A.T. CHEMISTRY - 12 Grades CHAPTER 18 - CHEMICAL EQUILIBRIUM

E-LEARNING SECTION
FILMS
In this section of e-learning while watching films about the chapter topics, the idea is to show systems that are in equilibrium, opposing processes occur at the same time and at the same rate.
The creation of stalactites and stalagmites is the result of a reversible chemical reaction.

Chemical Equilibria and Reaction Quotients

Many chemical reactions do not just go one way, they go forwards and backwards. Once there is balance between the two, this is equilibrium. In addition, we need to be able to predict how much stuff there will be at equilibrium! Get ready to bust out those ICE boxes, folks.

How To Calculate The Equilibrium Constant K - Chemical Equilibrium Problems & Ice Tables

This chemistry video tutorial provides a basic introduction into how to solve chemical equilibrium problems. It explains how to calculate the equilibrium constant k value given the equilibrium concentrations and equilibrium partial pressures of all reactants and products. If explains how to calculate the equilibrium constant k for a new reaction by changing another reaction.
Finally, it discusses how to calculate the equilibrium constant k using ice tables.

This chemistry video tutorial focuses on the reaction quotient Q and the equilibrium constant K. It shows you how to determine in which direction the reaction will shift. It contains a few examples and one practice problem.

Here is a list of topics:

1. Reaction Quotient Q - Initial Concentration / Partial Pressure Values
2. Equilibrium Constant K - Equilibrium Values
3. How To Determine If the Reaction Will Shift to the left or to the right
4. If Q is less than K, it shifts to the right
5. If Q is greater than K, it shifts to the left
6. If Q equals K, the system is at equilibrium
7. Reactant Favored vs. Product Favored Situations
8. How To Write The Equilibrium Expression
9. Ice Table Product - No Quadratic Equation
10. How To Calculate the Equilibrium Partial pressures Using an ICE Table and the Reaction Quotient Q
    

Factors Affecting the Rate of the Reaction - Chemical Kinetics

The CHEMICAL EQUILIBRIUM is being related to many factors affecting the chemical reaction, at which this chemistry video tutorial discusses five factors affecting the rate of a reaction. This includes the nature of the reactants, concentration, surface area, temperature, and the use of a catalyst.
This tutorial is part of the chemical kinetics series.
