JEE MAIN - Chemistry (2002 - No. 31)
Conductivity (Seimen’s S) is directly proportional to area of the vessel and the concentration
of the solution in it and is inversely proportional to the length of the vessel then, then constant of proportionality is expressed in :
Sm mol-1
Sm2 mol-1
S-2m2 mol
S2m2 mol-2
Explanation
Given $$S \propto {{area\, \times \,conc} \over \ell } = {{\kappa {m^2}mol} \over {m \times {m^3}}}$$
$$\therefore$$ $$\,\,\,\,\kappa = S{m^2}mo{l^{ - 1}}$$
$$\therefore$$ $$\,\,\,\,\kappa = S{m^2}mo{l^{ - 1}}$$
