30. Which one of the following will change the value of an equilibrium constant, K? A) changing the temperature B) adding other substances that do not react with any of the species involved in the equilibrium C) varying the initial concentration of reactants D) varying the initial concentration of products E) all of these 31. The reaction, 4+BX+Y, has K₂=997 at 472 K. At equilibrium A) the reaction is product favored B) the reaction is reactant favored C) roughly equal amounts of products and reactants are present D) only products exist E) only reactants exist 32. Which of the reactants and/or products do not appear in the properly written heterogeneous K, expression for the reaction: NiCO₂ (s) + 2H* (aq) = Ni (aq) + CO(g) + H₂O(l) A) NICO3(s) only B) CO₂(g) and H₂O(l) C) H*(aq) and Ni²(aq) D) CO₂(g) only E) NICO3(s) and H₂O (1) 33. For the endothermic reaction: CaCO,(s)=CaO(s)+CO,(g) only_would favor shifting the equilibrium position to form more CO₂(g). A) increasing the system temperature B) decreasing the system temperature C) increasing the system pressure D) increasing both the system temperature and the system pressure E) both decreasing the system temperature and increasing the system pressure 30.
