Abstract

High school and beginning students begin with a concrete operation of moving piles of small objects between two piles. Initially one set of rate constants for the movement is given, and the size of the piles is determined in subsequent rounds until the size of the piles stabilizes. Subsequently the effects of other factors, such as the initial size of the piles and the ratio of the forward and reverse rates on the final equilibrium may be examined. An opportunity to develop a computer analysis is also given.
