The initial rate of hydrolysis of methyl acetate (1 M) by a weak acid (HA, 1 M) is 1 / 10 0 t h of that of a strong acid (HX, 1M), at 25°C. The K a of HA is

Options

  1. A1 × 1 0 - 4
  2. B1 × 1 0 - 5
  3. C1 × 1 0 - 6
  4. D1 × 1 0 - 3

Correct answer

A. 1 × 1 0 - 4

Step-by-step solution

K a = C α 2 = 1 × ( 0.01 ) 2 = 1 × 1 0 - 4
