The symbols have their usual meaning, for example AG stands for thestandard 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 nextit. Otherwise, check the "no false statements" box under the table.statementfalse?statementfalse?AG > 0In K-0K<1K-1In K<0AG-TASAH TASAG-0no false statements:no false statements:
