Question 1

If you know Kb for ammonia, NH3, you can calculate the equilibrium constant, Ka, for the following reaction: NH4+ NH3 + H+ by the equation:

◦ Ka = Kw× Kb.
◦ Ka = Kw / Kb.
◦ Ka = 1 / Kb.
◦ Ka = Kb / Kw.
◦ None of these are correct.

Question 2

In a solution prepared by dissolving 0.100 mole of propanoic acid in enough water to make 1.00 L of solution, the pH is observed to be 2.793. The Ka for propanoic acid (HC3H5O2) is:

◦ 1.61 × 10–3.
◦ 2.60 × 10–5.
◦ 1.64 × 10–2.
◦ 3.79 × 10–10.
◦ None of these are correct.
