Classroom Resources: Kinetics
1 – 3 of 3 Classroom Resources
Catalysts, Molecular Structure | High School
The compound ozone, a known respiratory irritant, exists in high concentrations at flight altitudes, making the “fresh air” sucked in by air conditioners at those heights, well, not so fresh. In fact ozone exposure may be responsible for many of the short-term discomforts we associate with air travel. What’s more, ozone can react with other compounds in the air -- even the oils of our skin -- to produce other toxic compounds, like aldehydes and ketones. Some planes have catalytic converters, like the ones in cars, which use transition metals to turn ozone into breathable oxygen. But not every plane has one!
Reaction Rate, Reaction Rate | Middle School, High School
In the May 2018 simulation, students investigate several factors that can affect the initial rate of a chemical reaction, including concentration, temperature, surface area of the reactants, and addition of a catalyst.
Catalysts, Reduction, Combustion, Redox Reaction, Activation Energy, Oxidation | Elementary School, Middle School, High School
This video investigates the role of a catalytic converter and its corresponding chemical reactions within a vehicle. Students will learn about both oxidation and reduction reactions and how they, in combination with a catalyst, can impact the molecules released in a car’s exhaust.
