Given below are two statements:
| Assertion (A): | Molar conductivity increases with a decrease in concentration. |
| Reason (R): | For strong electrolytes, \(Λ_m\) increases slowly with dilution and can be represented by the equation: \(\Lambda_m=\Lambda_m^0-A c^{1 / 2}\) |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
