Molar conductivity (Λm) increases as the concentration of the electrolyte decreases. This is because at lower concentrations, the ions experience less interionic attraction and can move more freely, increasing conductivity per mole of electrolyte.
Among the given concentrations, 0.001 M is the most dilute solution and thus has the highest molar conductivity.
Correct Answer: 0.001 M
For the given cell: \[ {Fe}^{2+}(aq) + {Ag}^+(aq) \to {Fe}^{3+}(aq) + {Ag}(s) \] The standard cell potential of the above reaction is given. The standard reduction potentials are given as: \[ {Ag}^+ + e^- \to {Ag} \quad E^\circ = x \, {V} \] \[ {Fe}^{2+} + 2e^- \to {Fe} \quad E^\circ = y \, {V} \] \[ {Fe}^{3+} + 3e^- \to {Fe} \quad E^\circ = z \, {V} \] The correct answer is:
Read the following statements: Statement I: All vertebrates develop a row of vestigial gill slits during embryonic stage.
Statement II: Embryos always pass through the adult stages of other animals.
