Question 1

What is the approximate value of the equilibrium constant, Kn, for the neutralization of pyridine with hydrochloric acid, shown in the equation below? The Kb for pyridine is 1.8 × 10-9.

HCl(aq) + C5H5N(aq) ⇌ C5H5NHCl(aq)

◦ 5.6 × 10-10
◦ 5.6 × 10-6
◦ 5.6 × 108
◦ 1.8 × 105

Question 2

What is the approximate value of the equilibrium constant, Kn, for the neutralization of nitrous acid with ammonia, shown in the equation below? The Ka for HNO2 is 4.5 × 10-4 and the Kb for NH3 is 1.8 × 10-5.

HNO2(aq) + NH3(aq) ⇌ NH4NO2(aq)

◦ 4.5 × 1010
◦ 8.1 × 105
◦ 8.1 × 1019
◦ 1.8 × 109
