Which of the following processes have a AS>0? A) CH₂OH(1) → CH₂OH(s) B) N2(g) + 3H2(g) → 2NH (g) c) CH2(g) + H2O(g) → CO(g) + 3H2(g) D) Na2CO3(s) + H2O(g) + CO2(g) →2NaHCO3(s) E) All of the above processes have a positive value for AS Consider a reaction that has a negative AH and a positive AS. Which of the following statements is true? A) This reaction will be spontaneous only at high temperatures. B) This reaction will be spontaneous at all temperatures. c) This reaction will be nonspontaneous at all temperatures. D) This reaction will be nonspontaneous only at high temperatures. E) It is not possible to determine without more information. If solid barium hydroxide octahydrate is mixed in a beaker with solid ammonium chloride, they reac highly endothermic process that absorbs so much heat from the surroundings that water on the out the beaker freezes: This reaction is: Ba(OH)2*8H2O(s) + 2NH4Cl(s) → BaCl2(aq) + 2NH3(g) + 10 H₂O(1) A) Never spontaneous B) Always spontaneous C) Spontaneous because of the large increase in entropy
