Le Chateliers Philosophy

What you can expect to learn from this page:

To be able to listen and identify Le Chatelier's three specific rules through a musical lecture.

- Concentration Change Rule

- Pressure Change Rule

- Temperature Change Rule

 

Background Summary:

To understand the concepts that are mention or explained through the song, the learner must understand:

- Reaction Rates
The rate that a chemical reacts with another chemical to create a specific product.

- Catalysts
To understand the use of chemicals that re-orientate the reactants to react better with the products. Also, catalysts affect these reactions in forwards and backwards direction equally so it is not accounted for in the Equilibrium equation.

- Activation Energy:
To understand that a specific amount of energy is needed to have a reaction occur.

- Equilibrium:
Having the dynamic change of the ratios of the reactants equaled with the ratio of change of the products.

- Equilibrium Constant
The amount of moles which the equilibrium ratios are equal. This amount is of course constant.

 

The act of learning causes the student to understand multiple types of teaching styles. By learning how to listen, then being able to derive the main aspects of a subject, the student will have the ability to grow quicker as a student of knowledge.

Homework (if any):

Below are a few assessing questions to test your knowledge of Le Chatlier's Philosophy

1. According to Le Chatlier's Philosophy, a system will not change due to the addition of an outside force.

- True

- False

 

A. The answer is false. A system dynamically changes when a force is added to an equalized system to try to re-establish a dynamic equilibrium.

 

2. How does a endothermic system change at equilibrium when the temperature increases?

- The equation shifts to the Products.

- The equation shifts to the Reactants.

 

A. The equation shifts to the Products. A system dynamically changes when a force is added to an equalized system to try to re-establish a dynamic equilibrium.

 

3. How does a exothermic system change at equilibrium when the temperature increases?

- The equation shifts to the Products.

- The equation shifts to the Reactants.

 

A. The equation shifts to the Reactants. Le Chat's states that a equation will relieve the stress by shifting to the side with less stress. In this case the Reactants have less stress.

 

4. How does a endothermic system change at equilibrium when the temperature decreases?

- The equation shifts to the Products.

- The equation shifts to the Reactants.

 

A. The equation shifts to the Reactants. The question is the opposite shift to Question 2.

 

5. How does a exothermic system change at equilibrium when the temperature decreases?

- The equation shifts to the Products.

- The equation shifts to the Reactants.

 

A. The equation shifts to the Products. The question is the opposite shift to Question 3.

 

6. What does Le Chat's Philosophy describe will occur if a chemical is a solid in a equalized equation?

- The equation shifts to the Products.

- The equation shifts to the Reactants.

- The philosophy doesn't apply to solids.

 

A. This philosophy does not apply to solids.
