Lesson Summary

Graph of nitrous oxide concentrations over time showing a general upward trend since 1980.This lesson addresses reaction kinetics and collision theory in the context of research into bacterial denitrification processes under varying conditions. It promotes student understanding of temperature effects on reaction rate and informs students about how kinetics can be applied to understand phenomena related to climate change.

Upon completion of this lesson, students will be able to: 

  • create and analyze graphs related to rates of a chemical reaction in order to understand temperature effects on the reaction.
  • explain how reaction-rate data can be used to study a natural process that could potentially be used to reduce levels of a greenhouse gas.
