Assertion: When Molar conductivity for a strong electrolyte is plotted versus \(\sqrt{C}(\mathrm{~mol} / \mathrm{L})^{1 / 2}\), a straight line is obtained with intercept equal to Molar conductivity at infinite dilution for the electrolyte and Slope equal to \(-\mathrm{A}\). All electrolytes of a given type have the same \(\mathrm{A}\) value.
Reason: At infinite dilution, strong electrolytes of the same type will have different number of ions due to incomplete dissociation.COMEDK 2024 Medium - \(\mathrm{N}_2 \mathrm{O}_5\) decomposes to \(\mathrm{NO}_2\) and \(\mathrm{O}_2\) and follow first order kinetics.
