Classify each of the statements as true or false. False Truc An exothermic reaction is always spontaneous. The entropy ofa substance increases when a solid melts into a liquid at any temperature. Product formation is never favored in a reaction with a negative AH and a positive AS. For an endothermic reaction, a decrease in temperature results in a decrease in the equilibrium constant. A reaction will have an equilibrium constant that is less than one if AG" for the reaction is positive. Entropy increases as the temperature decreases. Answer Bank 2°C Mostly cloudy A a ENG 01/0
For the reaction CO(g) + 3H2(g)- →CH4(g) + H,O(g) AH° = -206.1 kJ and AS° = -214.7 J/K The equilibrium constant for this reaction at 290.0 K is Assume that AH° and AS° are independent of temperature.
