Abstract

An educational lattice model is proposed for the investigation of the influence of the density and indirectly of thepressure on the chemical equilibrium of the ideal gas phase reaction A???2B. The model can be introduced by a board gamesimulating a stochastic process. This game can also be used to set up a corresponding computer algorithm. The solutions of thismodel by stochastic simulations are compared to the analytical solutions for the equilibrium state and to the numerical solution ofthe corresponding differential equation. It is the aim of this approach to introduce examples of the scientific method of simulation atan early stage of chemical education such as secondary education using a simple model. It furthermore allows students to deepentheir understanding of chemical equilibria and the Le Cha??telier density as well as pressure effect on the equilibrium at that level.
