A. Both the assertion and reason are true and reason is the true explanation for assertion.
B. Both the assertion and reason are true and reason is not the true explanation for assertion.
C. Assertion is true but reason is false.
D. Assertion is false and reason is true
E. Both Assertion and reason are false.

Answer 1

Hint: We know that at endless dilution the comparable conductance of cations and anions are free of one another. At endless weakening, frail and solid electrolytes have a level of separation equivalent to 1.

Complete step by step answer:
The molar conductance of Strong electrolyte just as powerless electrolytes increases with decline in focus or expansion in weakening. The variety is anyway extraordinary for solid and frail electrolytes.
The variety of molar conductance with focus can be clarified based on the leading capacity of particles for feeble and solid electrolytes. For feeble electrolytes, the variety of with weakening can be clarified on the basis of the number of particles in arrangement. The quantity of particles outfitted by an electrolyte in arrangement relies on the level of separation with weakening. With the expansion in weakening, the level of separation increments and therefore, molar conductance increments. The restricting estimation of molar conductance compares to level of separation equivalent to 1 i.e., the entire of the electrolyte separates.

So, the correct answer is Option A.

Note: By and large, conductance of an electrolyte relies upon the accompanying variables,
(1) Nature of electrolyte: The conductance of an electrolyte relies on the quantity of particles present in the arrangement. Subsequently, the more prominent the quantity of particles in the arrangement the more noteworthy is the conductance. The quantity of particles delivered by an electrolyte relies on its tendency. The solid electrolytes separate totally into particles in arrangements and, accordingly, their answers have high conductance. Then again, feeble electrolytes separate to just little degrees and give fewer numbers of particles. In this way, the arrangements of powerless electrolytes have low conductance.
(2) Concentration of the arrangement: The molar conductance of electrolytic arrangement shifts with the convergence of the electrolyte. By and large, the molar conductance of an electrolyte increments with decline in fixation or expansion in weakening.
