In which of the following aqueous systems would you expect AgCl to have the greatest solubility? Hint: Do not forget to consider acid-base properties of salts. 

The reaction A(l) → B(g) + C(g) is shown to be exothermic. Which of the following is true concerning the reaction?

The diagrams here represent solutions at various stages in the titration of a weak base B (such as NH3) with HCl. Which image best represents the solution in the buffer zone between the initial and equivalence points?                                                               

Methane gas can be produced by the reaction of solid carbon with hydrogen gas as follows                     C(s)   +   2 H2(g)  ⇌   CH4(g) For this reaction at equilibrium, Kp =  0.38.  A vessel containing carbon is sealed and injected inititally with hydrogen to a pressure of 2.0 atm and with methane to a pressure of 2.0 atm. What happens as the reaction proceeds toward equilibrium?  Hint:  this is a K vs Q question.  Which way will the reaction proceed to reach equilibrium?

Consider the titration of 50.0 mL of 0.10 M HClO4 with KOH.   What is the pH after 20.0 mL of 0.50 M KOH has been added?

An example of a reaction that experiences a decrease in entropy, ΔS < 0, yet is spontaneous because of the release of a large quantity of heat, ΔH = −151 kJ, is the formation of solid ammonium nitrate from the reaction of gaseous nitric acid with gaseous ammonia.                        HNO3(g)   +   NH3(g)   →  NH4NO3 (s) The change in free energy under standard condition is: ΔG° =  −93. kJ/mol.  Calculate the equilibrium constant, K, for the reaction at T = 298 K.
