Chapter 18, Problem 104A

Interpretation Introduction

Interpretation: The purpose of the speed bump and its similarity with activation energy is to be explained.

Concept introduction: The activation energy refers to the minimal amount of additional energy a reactive molecule needs to transform into a product during a chemical reaction.

Answer to Problem 104A

Speed bumps are more effective for traffic calming. Speed bumps function as an activation energy barrier for vehicles to regulate their speed.

Explanation of Solution

Speed bumps are a more aggressive way to slow down traffic than speed humps. They are useful in places like parking lots and driveways where cars and people share space.

The activation energy and speed of a chemical reaction are closely related. Specifically, the chemical reaction will be slower the greater the activation energy. Speed bumps serve as an activation energy barrier for controlling the speed of vehicles.

Conclusion

Speed bumps are more effective for traffic calming. Speed bumps function as an activation energy barrier for vehicles to regulate their speed.
