Chemistry Question from JEE Main 2025 · 28 January, Shift 1

Given below is the plot of the molar conductivity vs c\sqrt{c} concentration for KCl in aqueous solution. If, for the higher concentration of KCl solution, the resistance of the conductivity cell is 100Ω100 \, \Omega, then the resistance of the same cell with the dilute solution is 'x' Ω\Omega. The value of xx is:

Plot of molar conductivity versus square root of concentration for KCl showing values 150 and 100, with corresponding sqrt(c) values 0.1 and 0.15, and a decreasing straight line.
