Assertion: equivalent conductance rises on dilution while specific conductance falls. Reason: dilution reduces the number of ions in a given volume but increases the fraction dissociated.

  • A.the assertion is false although the reason offered is a true statement in itself
  • B.both the assertion and the reason are true and the reason explains the assertion
  • C.both the assertion and the reason are true but the reason does not explain the assertion
  • D.the assertion is true but the reason given for it is false

Answer: B

The specific measurement is on a fixed volume and so follows the ion concentration downward, while the equivalent measurement is on a fixed amount of solute and so follows the dissociation upward. The reason accounts for both halves.
