The resistance of a conductivity cell filled with 0.02 M KCl solution is 85 \(\Omega\) at \(25^{\circ}C\). Conductivity of this solution is \(0.3 \text{ S m}^{-1}\). Resistance of 0.0025 M \(K_2SO_4\) solution taken in the same cell is 300 \(\Omega\). The molar conductivity of 0.0025 M \(K_2SO_4\) solution (in S \(\text{m}^2 \text{mol}^{-1}\)) is:

In a flask, 2 g of activated charcoal was added to 100 mL of acetic acid solution of 0.06 N. After 2 hours, the solution was filtered. The concentration of filtrate was found to be 0.04 N. The mass of acetic acid (in mg) adsorbed per gram of charcoal is:

Given below are two statements:
Statement - I: London forces between two particles are proportional to \(r^{-6}\), where 'r' is the distance between two particles.
Statement - II: The dipole-dipole interaction energy in a solid is proportional to \(r^{-3}\) where r is the distance between two polar molecules.

If a graph is drawn between \(log(x/m)\) (y-axis) and log p (x-axis) we get a straight line with slope equal to 2 and intercept equal to 0.60. The value of x/m at 9 atm is (\(log 4=0.60\))
