Conductance ‘

C

’ (in

S

) in directly proportional to the area of the electrode and concentration and inversely proportional to length of separation of electrode, the unit of constant of proportionality is:

View answer and explanation

Correct option: B

\mathrm{S}{\kern 1pt} {\kern 1pt} {\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{mo}{\mathrm{l}^{ - 1}}

Option B is correct because the constant of proportionality is conductivity, and its unit is S m² mol⁻¹ when conductance is directly proportional to area and concentration and inversely proportional to length.
