Conductance (with unit slemens S) is dir...

Conductance (with unit slemens S) is directly proportional to area f the electrode plates and the concentration of the solution in the cell and is inversely proportional to the separation between the electrodes plates. Then the unit of the constant of proportionally is:

A

`S m "mol"^(-1)`

B

`S m^(2) "mol"^(-1)`

C

`S^(-2)m^(2)"mol"`

D

`S^(2)m^(2)"mol"^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Conductivity `prop("Area"xx"Concentration")/("Length")`
or Conductivity `=kxx("Area"xx"Concentration")/("Length")`
Units of `K=(Sm^(-1)xxm)/(m^(2)xx"mol"m^(-3))=s m "mol"^(-1)`
[units of conductivity are `Sm^(-2)`]
