Step-by-step solution
(i) Molar conductivity is defined as the conductivity of a solution containing one mole of an electrolyte. Therefore, it is directly related to: P) Molarity (ii) Conductivity of an electrolyte solution increases with concentration, but molar conductivity increases with dilution and reaches a limiting value. This limiting value is: R) Limiting molar conductivity (iii) Degree of dissociation ( ( )) is related to the molar conductivity ( ( m )) and limiting molar conductivity ( ( ^ m )) through the equation: ( = m / ^
