Question

Which of the following statements is correct about ${\lambda }_a^{\infty }$ or ${\lambda }_c^{\infty }$ (i.e., ionic conductivities)?

• A. Increases with temperature due to increase in viscosity of medium.
• B. Increases with pressure due to decrease in viscosity of medium.
• C. Decreases with pressure due to increase in viscosity of medium.
• D. Decreases with pressure due to decrease in viscosity of medium.

Answer 1

Answer: (C)

Decreases with pressure due to increase in viscosity of medium.

Increase in temperature decreases viscosity, whereas increase in pressure increases viscosity of the medium.
Following statements are correct about ionic conductivities ${\lambda }_a^{\infty }$ or ${\lambda }_c^{\infty }$.
Increases with temperature due to decrease in viscosity of the medium.
Decreases with pressure due to increase in viscosity of the medium.
