# Reaction Rates

##### Stage: 5 Challenge Level:

Starting with concrete examples is a good way to get into this problem.

To get a feel for the rate equation and how to solve it, think of a function and evaluate both sides of the equation. If they are the same for a particular choice of $m$ then you have found a solution (well done!). If not, how might you adjust the function to turn it into a solution?
