Summary

In this Spreadsheets Across the Curriculum activity, students create spreadsheets to examine the time course of a reaction that goes to completion and compare it to the time course of a reaction that reaches equilibrium. Students input both the rates of the forward and the reverse reactions into the spreadsheets and study the relationship between relative reaction rates and the extent of reaction completion.
