Lesson Title: Today we are learning about
How do temperature and pressure affect the rate of a chemical reaction?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Collision theory explains how various factors affect rates of reactions. According to this theory, chemical reactions can occur only when reacting particles collide with each other and with sufficient energy. Factors which affect the rates of chemical reactions include: the concentrations of reactants in solution, the pressure of reacting gases, the surface area of solid reactants, the temperature and the presence of catalysts. The minimum amount of energy that particles must have to react is called the activation energy. Increasing the temperature increases the frequency of collisions and makes the collisions more energetic, and so increases the rate of reaction. The minimum amount of energy that particles must have to react is called the activation energy. Students should be able to recall how changing the pressure of reacting gases affects the rate of chemical reactions. Students should be able to recall how changing the temperature affects the rate of chemical reactions.

AFL/Key Questions:

What are the main principals of the collision theory?
Collision theory explains how various factors affect rates of reactions. According to this theory, chemical reactions can occur only when reacting particles collide with each other and with sufficient energy.
What factors can affect the rate of a chemical reaction?
Factors which affect the rates of chemical reactions include: the concentrations of reactants in solution, the pressure of reacting gases, the surface area of solid reactants, the temperature and the presence of catalysts.
What does the term activation energy mean?
The minimum amount of energy that particles must have to react is called the activation energy.
How does increasing the temperature increase the rate of a chemical reaction?
Increasing the temperature increases the frequency of collisions and makes the collisions more energetic, and so increases the rate of reaction.
How does increasing the pressure of reacting gases affect the rate of a chemical reaction?
Increasing the pressure of reactant gases increases the rate of chemical reactions.
How does decreasing the temperature of a chemical reaction affect the rate?
Decreasing the temperature of a chemical reaction decreases the rate of the reaction.
