A. If 139 L of 18.0 M H2SO4(aq) is diluted to a final volume of 5.00 L, what is the pH of the resultant solution? B. Consider the following reaction: A(g) B(g) where Keq = 1.0 x 10-2. Which of the following statements are true at equilibrium? C. Consider the following reaction at equilibrium: 2A + 2B 2C + 2D + E If the concentration [E] is suddenly changed by a factor of two (halving [E]), what can be said about the changes in [A] and [B]? D. Consider the following chemical reaction: A+B C + 2D When Q < Keq for the above reaction, which of the following is true? E. Suppose 5.0 L of a solution of HBr(aq) is prepared. What will be the [HBr] at equilibrium in this solution its pH is measured to be 1.85?
