CsCl crystallises in body centred cubic lattice. If 'a' is its edge length then which of the following expressions is correct?

Consider separate solutions of 0.500 M $$C_2H_5OH$$ (aq), 0.100 M $$Mg_3(PO_4)_2$$ (aq), 0.250 M KBr (aq) and 0.125 M $$Na_3PO_4$$ (aq) at 25 °C. Which statement is true about these solutions, assuming all salts to be strong electrolytes?

Resistance of 0.2 M solution of an electrolyte is 50 $$\Omega$$. The specific conductance of the solution is 1.4 S m$$^{-1}$$. The resistance of 0.5 M solution of the same electrolyte is 280 $$\Omega$$. The molar conductivity of 0.5 M solution of the electrolyte in S m$$^2$$ mol$$^{-1}$$ is:

The equivalent conductance of NaCl at concentration C and at infinite dilution are $$\lambda_C$$ and $$\lambda_{\infty}$$, respectively. The correct relationship between $$\lambda_C$$ and $$\lambda_{\infty}$$ is given as: (where the constant B is positive)

The metal that cannot be obtained by the electrolysis of an aqueous solution of its salt is:

Given below are the half-cell reactions:
$$Mn^{2+} + 2e^- \to Mn$$; $$E^\circ = -1.18$$ V
$$2(Mn^{3+} + e^- \to Mn^{2+})$$; $$E^\circ = +1.51$$ V
The $$E^\circ$$ for $$3Mn^{2+} \to Mn + 2Mn^{3+}$$ will be:

For the non-stoichiometry reaction, $$2A + B \to C + D$$, the following kinetic data were obtained in three separate experiments, all at 298 K.
Initial Concentration   Initial Concentration  Initial rate of formation of C
(A)                                   (B)                                (mol L$$^{-1}$$ S$$^{-1}$$)
0.1 M                               0.1 M                          $$1.2 \times 10^{-3}$$
0.1 M                               0.2 M                          $$1.2 \times 10^{-3}$$
0.2 M                               0.1 M                          $$2.4 \times 10^{-3}$$

The rate law for the formation of C is:
