Two statements, one Assertion and the other Reason are given. Choose the right option. Assertion: The Molar conductivity of KCl increases very slowly with dilution and approaches a limiting value when dilution is infinite. Reason: In case of KCl there is an increase in the number of ions on dilution due to complete ionisation at infinite dilution.

Step-by-step solution

KCl is a strong electrolyte and is completely ionised in solution at all concentrations. Therefore, the number of ions does not increase upon dilution. The molar conductivity of a strong electrolyte like KCl increases slowly with dilution and approaches a limiting value at infinite dilution ( _m^ ). This increase is not due to an increase in the number of ions, but rather due to a decrease in interionic attractions, which increases the mobility of the ions. Thus, the Assertion is correct, but the Reason is incorrec
