The statements in the tables below are about two different chemical equilibria. The symbols have their usual meaning, for example AGO stands for the standard Gibbs free energy of reaction and K stands for the equilibrium constant. In each table, there may be one statement that is false because it contradicts the other three statements. If you find a false statement, check the box next to it. Otherwise, check the "no false statements" box under the table. statement In K0 AH
