Plotting 1/ Λ m against cΛ m for aqueous solutions of a monobasic weak acid (HX) resulted in a straight line with y - axis intercept of P and slope of S. The rat io P ⁄S is [ Λ m = molar conductivity o m  = limiting molar conductivity c = molar concentration K a = dissociation constant of HX]

1. K a o m 
2. K a o m  /2
3. 2 K a o m 
4. 1/(K a o m  )

Correct answer: K a o m 
