Any of the first three can be the independent variable; the dependent variable is usually reaction rate. Examples:

- The purpose of this experiment was to investigate how temperature affects reaction rate.
- The purpose of this experiment was to investigate how surface area affects reaction rate.
- The purpose of this experiment was to investigate how concentration affects reaction rate.

Choose the one that matches the variable you actually changed in the experiment.
