Calculating an equilibrium concentration

This page is an exercise in calculating an equilibrium concentration from a balanced equation, the K value and a partial set of equilibrium concentration. For purposes of this page, all species shown in the balanced reaction will appear in the eqation for Q. When you press "New Question" a a balanced equation, a K value and a partial set of equilibrium concentrations will be displayed to the right of the table. Use the information provided to determine the value of the missing concentration. Enter it in the answer cell and press "Check Answer." The results will appear in the table on the main page.
