Redox Reactions And Electrochemistry Ques 79

Question: If equivalent conductance of $1 M$ benzoic acid is $12.8 o h m^{- 1} c m^{2}$ and if the conductance of benzoate ion and $H^{+}$ ion are 42 and $288.42, o h m^{- 1} c m^{2}$ respectively. its degree of dissociation is [DPMT 2005]

Options:

A) 39%

B) 3.9%

C) 0.35%

D) 0.039%

Show Answer

Answer:

Correct Answer: B

Solution:

$Λ_{m, (C_{6} H_{5} C O O H)}^{o} = Λ_{, (C_{6} H_{5} C O O^{-})}^{o} + Λ_{(H^{+})}^{o}$ $= 42 + 288.42 = 330.42$ $α = \frac{Λ_{m}^{c}}{Λ_{m}^{o}} = \frac{12.8}{330.42} = 3.9$
