The tool on this page is a simplified equilibrium simulator intended to help students to understand chemical equilibria, by allowing them to study a reaction, A + B → C, and its reverse reaction, the decomposition of C → A + B. The simulator can be used to illustrate the impact of changing the initial ratio of the reactants, as well as adjusting the rate of the revese reaction (decomposition of C). read more
