A certain reaction has ΔH∘=35.4kJ and ΔS∘=85.0J/K. You may want to reference (Pages 831 - 832) Section 19.6 while completing this problem. Part APart complete Is the reaction exothermic or endothermic? exothermic endothermic Previous Answers Correct A positive enthalpy value indicates that energy is absorbed by the system. Therefore, the reaction is endothermic. Part BPart complete Does the reaction lead to an increase or decrease in the disorder of the system? increase decrease Previous Answers Correct The sign of the entropy change is positive, which indicates that the disorder, or entropy, of the system has increased. Part C Calculate ΔG∘ for the reaction at 298 K.
