Classify each of the statements as true or false. True False Answer Bank Entropy decreases as the temperature increases. The entropy of a substance decreases when a gas condenses into a liquid at any temperature. A reaction will have an equilibrium constant that is greater than one if AG° for the reaction is negative. For an exothermic reaction, an increase in temperature results in a decrease in the equilibrium constant. Product formation is always favored in a reaction with a negative AH° and a negative ASº. An exothermic reaction is always spontaneous.
