Question 1

The equilibrium constant for the reaction
         C6H5COOH(aq) + CH3COO(aq) C6H5COO(aq) + CH3COOH(aq)
is 3.6 at 25°C.  If Ka for CH3COOH is 1.8 × 10–5, what is the acid dissociation constant for C6H5COOH?
◦ 5.0 × 10–6

◦ 6.5 × 10–5

◦ 2.3 × 10–4

◦ 8.3 × 10–5

◦ 5.6 × 10–6


Question 2

The equilibrium constant for the reaction
         C7H15COOH(aq) + HCOO(aq) C7H15COO(aq) + HCOOH(aq)
is 7.23 × 10–2 at 25°C.  If Ka for formic acid (HCOOH) is 1.77 × 10–4, what is the acid dissociation constant for C7H15COOH?
◦ 2.45 × 10–3

◦ 4.08 × 10–2

◦ 7.81 × 10–4

◦ 1.00 × 10–4

◦ 1.28 × 10–5
