Chemistry Question on Conductance

The unit of equivalent conductivity is

A

ohm cm

B

ohm−1cm2(g−eq)−1ohm ^{-1} cm ^{2}( g - eq )^{-1}

C

ohm−1 cm+2(g equivalent)−1ohm^{-1} \, cm^{+2} (g\, {\text{equivalent}})^{-1}

D

S cm2S\, cm^2

Answer

ohm−1cm2(g−eq)−1ohm ^{-1} cm ^{2}( g - eq )^{-1}

Explanation

Solution

Aeq=k×1000/c=k×100/CA _{ e q }= k \times 1 0 0 0 / c = k \times 1 0 0 / C where Aeq=A _{ eq }= equivalent conductance C=C = concentration in eq/L ∴\therefore Units of Aeq A _{\text {eq }} are ohm −1cm2(g−eq−1)^{-1} c m ^{2}\left( g - e q ^{-1}\right)
