Catalyst 3/14/14• On your Catalyst Sheet, please answer the following
question:
1. Based on your Alka-Seltzer Rocket lab data, how does the amount of Alka-Seltzer affect the rate (speed) of the reaction?
2. Based on your Alka-Seltzer Rocket lab data, how does the temperature of the water affect the rate (speed) of the reaction?
• When you are done, raise your hand quietly for a stamp.

LECTURE 8.1 – RATES OF REACTION
![Page 4: Catalyst 3/14 /14](https://reader034.vdocument.in/reader034/viewer/2022051118/5681620b550346895dd237d5/html5/thumbnails/4.jpg)
Today’s Learning Targets• LT 8.2 – I can describe the rate of a reaction using
the ideas of concentration of reactants, concentration of products, and time. I can explain how the collision theory impacts rate of reaction.

Today’s Focus Question• What is the typical rate at which
food decomposes?

What is a reaction rate?
![Page 7: Catalyst 3/14 /14](https://reader034.vdocument.in/reader034/viewer/2022051118/5681620b550346895dd237d5/html5/thumbnails/7.jpg)
I. Rate of Reaction• A rate describes how fast something
changes with time.• Reaction rate is measured either by
the rate of formation of product or the rate of disappearance of the reactants.

What are ways to impact the rate of reaction?
![Page 10: Catalyst 3/14 /14](https://reader034.vdocument.in/reader034/viewer/2022051118/5681620b550346895dd237d5/html5/thumbnails/10.jpg)
I. Concentration, Temperature, Pressure, and Rate
• As concentration , the rate also increases
• As temperature , the rate also increases.
• As pressure , the rate also increases.
• This is due to the increased amount of collisions

How is collision theory related to rates?
![Page 12: Catalyst 3/14 /14](https://reader034.vdocument.in/reader034/viewer/2022051118/5681620b550346895dd237d5/html5/thumbnails/12.jpg)
I. Collision Theory• Reactions occur when molecules collide.• Therefore, more collisions, a faster overall
rate of reaction. Less collisions, a slower rate.

White Board QuestionsH2 + Cl2 2HCl
• If I increase the concentration of H2, how will the rate change?
• If I decrease the pressure, how will the rate change?
• I heat the container, how will the rate be changed?
• I decrease the amount of Cl2, how will the rate change?
