Friday, 22 November

How can graphical analysis of a chemical reaction rate allow us to determine reaction orders and half-lives?

In class

  1. Warm up exercise: Sulfur dioxide reacts with oxygen gas to form sulfur trioxide. If the initial rate of change for sulfur dioxide is -2.00 M/min, what is the initial rate of change of oxygen and sulfur trioxide?
  2. Explain what a rate law tells us about a chemical reaction and use graphical data to determine the reaction order.

Assignments

  1. Using the Reactions and Rates PhET simulation, answer Exercises 9 – 11 in Chapter 17 in your textbook.
  2. Work out answers to Exercises 1, 2, 4, and 32 in Chapter 17 in your text book.

Thursday, 21 November

In class

  1. Discuss how the collision theory model can be useful in partially explaining the rates of chemical reactions.
  2. Explain how certain variables affect the rate of a reaction according to the collision theory model.

Assignments

  1. Upload your group’s Rate v. Variable plot to the document.

Wednesday, 20 November

In class

  1. Set up your experiments and collect data.
  2. Begin analyzing your data and create graph(s).

Assignments

  1. Begin reading Chapter 17: Kinetics in your textbook. We will cover all the material in this chapter by the end of the unit.
Measure the change in pressure for a chemical reaction is one method to indirectly measure the relative rates of the chemical change.
Measure the change in pressure for a chemical reaction is one method to indirectly measure the relative rates of the chemical change.
Measure the change in pressure for a chemical reaction is one method to indirectly measure the relative rates of the chemical change.

Tuesday, 19 November

In class

  1. With your group, design the procedure for the reaction speed experiment.

Assignments

  1. Dress for laboratory work tomorrow.
  2. Begin work on the Rate of Reaction problem set. This paper will outline the ways chemists measure the speed of chemical reactions.

Monday, 18 November

Friday, 15 November

In class

  1. Prepare your laboratory notebooks for collection on Monday by putting a sticky note in the margins by the start of the Eight Chemical Reactions experiment so I can flip to it quickly.
  2. Form lab groups and discuss the central challenge of the How long will that marble statue last? experiment. Then, work your way through the rest of p. 83 and 84 brainstorming your ideas.
  3. Ask any final questions you have about the material for Monday’s test.

Outside of class

  1. Review and prepare for the Unit 4 exam on Monday.
