JEE Main 2024 (Online) 4th April Evening Shift | Electrochemistry Question 15 | Chemistry

For a strong electrolyte, a plot of molar conductivity against (concentration) $${ }^{1 / 2}$$ is a straight line, with a negative slope, the correct unit for the slope is

$$\mathrm{S} \mathrm{cm}^2 \mathrm{~mol}^{-3 / 2} \mathrm{~L}$$

$$\mathrm{S} \mathrm{cm}{ }^2 \mathrm{~mol}^{-3 / 2} \mathrm{~L}^{-1 / 2}$$

$$\mathrm{S} \mathrm{cm}{ }^2 \mathrm{~mol}^{-1} \mathrm{~L}^{1 / 2}$$

$$\mathrm{S} \mathrm{cm}^2 \mathrm{~mol}^{-3 / 2} \mathrm{~L}^{1 / 2}$$
