JEE Mains · Chemistry · STD 12 - 2. Electrochemistry
Given below are two statements : Statement \(I :\) The limiting molar conductivity of \(\mathrm{KCl}\) (strong electrolyte) is higher compared to that of \(\mathrm{CH}_{3} \mathrm{COOH}\) (weak electrolyte). Statement \(II :\) Molar conductivity decreases with decrease in concentration of electrolyte. In the light of the above statements, choose the most appropriate answer from the options given below:
- A Statement \(I\) is true but Statement \(II\) is false.
- B Statement \(I\) is false but Statement \(II\) is true.
- C Both Statement \(I\) and Statement \(II\) are true.
- D Both Statement \(I\) and Statement \(II\) are false.
