Depletion is a game with natural rules that reinforces central concepts of reaction rate theory through simulation. It is designed as a supplement to classroom instruction in introductory chemistry. The game’s rules simulate some characteristics of chemical reactions. The game board depicts a free energy landscape with five hills that represent the activation free energies of five sequential chemical reactions. Players buy reactants and guide them through the reactions, choosing whether or not to increase the chance of a successful reaction by buying additional heat or some catalyst. Players earn money when a reaction is successfully completed. At the end of the game, the player with the most money wins. A more complete discussion of this game has been published in the Journal of Chemical Education 79, 1232-1234 (2002).
