The degree of dissociation of 0.1M acid HA is 5%. The value of Kc of HA is

  1. A 1.3×10-4
  2. B 2.6×10-3
  3. C 2.5×10-4
  4. D 1.3×10-2
Verified Solution

Answer & Solution

Correct Answer

(C) 2.5×10-4

Step-by-step Solution

Detailed explanation

The formula of degree of dissociation is given by α = KcC where, Kc= equilibrium constant C=concentration Here, C=0.1 M,  α=5%=0.05 Putting in above formula, we get Kc=α2×C Kc=0.052×0.1Kc=2.5×10-4 M Hence, option C is…
