In case of the weal electrolyte it is not possible to calculate the molar conductivity at infinite dilution by extrapolation of the graph between the molar conductivity and the concentration,because there is large variation between them. As you can see from the graph:-

In case of weak electrolytes conductivity can be calculated by Kohlrausch law.

For weak electrolytes ∧mocannot to be calculated by extrapolatio...

Explanation:

The statement is asking for the reason why the molar conductivity (m0) of weak electrolytes cannot be calculated by extrapolation of movs (c)1/2 graph. The correct answer is option 'B', which is explained below:

Weak electrolytes do not ionize completely in solution

- Weak electrolytes ionize partially in solution, which means that only a small fraction of the solute molecules dissociate into ions.
- The degree of ionization depends on the concentration of the solution, as well as other factors such as temperature and solvent properties.
- This means that the molar conductivity of weak electrolytes does not follow a simple linear relationship with concentration, as would be expected for a completely ionized electrolyte.
- As a result, it is not possible to extrapolate the molar conductivity of a weak electrolyte from a plot of movs (c)1/2 graph.

Other options explained:

a) m0 increases steeply on dilution especially near lower concentrations.

- This statement is true for strong electrolytes, but not necessarily for weak electrolytes.
- Strong electrolytes ionize completely in solution, so their molar conductivity increases rapidly as the concentration decreases.
- Weak electrolytes, on the other hand, do not necessarily show a steep increase in molar conductivity on dilution.

c) m for weak electrolytes does not vary linearly with dilution.

- This statement is true, as explained above.
- The molar conductivity of weak electrolytes does not follow a simple linear relationship with concentration.

d) Weak electrolytes dissociated to a much lesser extent as compared to strong electrolytes and therefore, m0 of weak electrolytes is low. It becomes even low at lower concentration.

- This statement is true, as weak electrolytes ionize only partially in solution.
- As a result, their molar conductivity is lower than that of strong electrolytes.
- The molar conductivity of weak electrolytes also decreases at lower concentrations, as the degree of ionization decreases.

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given.
