Today’s Learning Target LT 8.3 – I can hypothesize about the impact that concentration, temperature, and pressure have on the rate of a chemical reaction.

McDonald’s French Fries Reading Read the article with your group. Answer the questions and be prepared to discuss with the class.

Reading Debrief What is decomposition? Why don’t McDonalds fries or burgers decompose? How can we slow the rate at which something decomposes? Should we be adding chemicals to our foods in order to preserve them? What other questions did you have during this reading?

Unit 8 – What is McDonald’s Putting In Its French Fries?

LECTURE 8.1 – FACTORS ON RATE OF REACTION

What are ways to impact the rate of reaction?

I. Concentration and Rate As you increase the concentration, the rate of reaction increases. The higher the concentration the more collisions that are occurring, which increases the rate.

II. Temperature and Rate As you heat up molecules they begin to move faster. The faster molecules move the more they collide, which means a faster rate.

III. Pressure and Rate As you increase the pressure molecules collide more into the wall of the container and into each other. Therefore, as you increase pressure, you increase the rate of the reaction.

Summarize Use the following words: Pressure Temperature Concentration Rate Collisions

Lab – Alka Seltzer Rockets Read and annotate the procedure for the lab

Lab Logistics You will be working in groups of 4 Decide who will take on each role: (1) Dropper (drops in tablet) (2) Capper (puts caps on test tube and turns upside down) (3) Cup Placer (places cup over test tube) (4) Timer/measurer

LAB DEMONSTRATION

Expectations Explain the influence of (1) concentration and (2) temperature influence the rate of a reaction of Alka Seltzer. You will turn in 1 COPY PER GROUP of your findings and post-lab questions at the end of class.

Lab Work Time

Post-Lab Analysis

Exit Ticket 1.Complete the following statements: a. As pressure increases, rate ____________ b. As temperature decreases, rate _________ c. As concentration increases, rate ________ 2. Pick one of the statements in a – c and explain why a change in rate is observed.

College-Ready Question: 2CO + O2  2CO2 If the above reaction takes place inside a sealed reaction chamber, then which of these procedures will cause a decrease in the rate of reaction? A raising the temperature of the reaction chamber B increasing the volume inside the reaction chamber C removing the CO2 as it is formed D adding more CO to the reaction chamber

Closing Time Turn in the lab questions as you leave. Work on your lab report!
