At \(98 \mathrm{~K}\), the conductivity of \(\mathrm{KCl}\) solutions of molarity \(0.1,0.01\) and \(1.0 \mathrm{M}\) are recorded as \(\mathrm{X}, \mathrm{Y}\) and \(\mathrm{Z}, \mathrm{Scm}^{-1}\) respectively. The correct relation between \(\mathrm{X}, \mathrm{Y}\) and \(\mathrm{Z}\) is
- A \(X>Y>Z\)
- B \(\mathrm{Z}>\mathrm{X}>\mathrm{Y}\)
- C \(Y>X>Z\)
- D \(X>Z>Y\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Z}>\mathrm{X}>\mathrm{Y}\)
Step-by-step Solution
Detailed explanation
With the increase in concentration, conductivity of solution increases due to an increase in the number of ions. Thus, \(\mathrm{Z}>\mathrm{X}>\mathrm{Y}\).
