Question

Accepted Answer

Correct answer: D. (d) Given, Λ=8 mho c m^2 Λ_∞=4 0 0 mho c m^2 Degree of dissociation, α= ΛΛ_∞ ⇒α= 84 0 0=2×1 0^−2 Dissociation constant, K=C α^2 Given, C=M l 3 2 K= 13 2×2×1 0^−2×2×1 0^−2 K=1.2 5×1 0^−5

$The equivalent conductance of M/32 solution of a weak monobasic acid is 8.0 mho c m^{2} and at infinite dilution is 400 mhos c m^{2} . The dissociation constant of this acid is$
