The reaction represented above goes essentially to completion. The reaction takes place in a rigid, insulated vessel that is initially at 600 K. 14. What happens to the temperature of the contents 46. What can be inferred about AS for the reaction at of the vessel as the reaction occurs? 600 K? (A) The temperature must increase, because (A) It must be positive, since the reaction is according to Le Châtelier's principle, an increase in temperature causes more products to form. thermodynamically unfavorable at 600 K (B) It must be negative, since there are more moles of products than reactants. C) It must be positive, since AG is negative (B) The temperature must decrease, because the (C) The temperature must decrease, because the (D) The temperature does not change, because the reaction takes place at a temperature above room temperature. and AH is positive. (D) It must be negative, since AG is positive and AH is positive reaction is endothermic. 47. Which of the following statements about the vessel is insulated bonds in the reactants and products is most accurate? . A sample of CH OHg) is placed in the (A) The sum of the bond enthalpies of the bonds previously evacuated vessel with a pressure of P, at 600 K. What is the final pressure in the vessel after the reaction is complete and the contents of the vessel are returned to 600 K? in the reactant is greater than the sum of the bond enthalpies of the bonds in the products (B) The sum of the bond enthalpies of the bonds
