Help please
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 The reaction, A + B X + Y, has K_c = 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 Which of the reactants and/or products do not appear in the properly written heterogeneous K_c expression for the reaction: NiCO_3 (s) + 2H^+ (aq) Ni^2+ (aq) + CO (g) + H_2O (l) A) NiCO_3(s) only B) CO_2(g) and H_2O(l) C) H^+(aq) and Ni^2+(aq) D) CO_2(g) only E) NiCO_3(s) and H_2O(l) For the endothermic reaction: CaCO_3(s) CaO(s) + CO_2(g) only _____ would favor shifting the equilibrium position to form more CO_2(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
