The distance between two electrodes of a cell is 2.5 cm and area of each electrode is

5\mathrm{ }c{m^2}

, then the cell constant (

in\mathrm{ }c{m^{ - 1}}

) is

View answer and explanation

Correct option: D

0.5

Option D is correct because the cell constant is the ratio of the distance between the electrodes to the area of the electrode, which is 2.5 cm / 5 cm² = 0.5 cm⁻¹.
