Vedclass · Answer

(C) According to Kohlrausch's law of independent migration of ions,the equivalent conductance at infinite dilution for benzoic acid $(C_6H_5COOH)$ can be calculated as follows:$\wedge_{C_6H_5COOH}^{\infty} = \wedge_{C_6H_5COONa}^{\infty} + \wedge_{HCl}^{\infty} - \wedge_{NaCl}^{\infty}$Given values:$\wedge_{C_6H_5COONa}^{\infty} = 240 \ \Omega^{-1} \ cm^2 \ equiv^{-1}$$\wedge_{HCl}^{\infty} = 349 \ \Omega^{-1} \ cm^2 \ equiv^{-1}$$\wedge_{NaCl}^{\infty} = 229 \ \Omega^{-1} \ cm^2 \ equiv^{-1}$Substituting the values:$\wedge_{C_6H_5COOH}^{\infty} = 240 + 349 - 229$$= 589 - 229$$= 360 \ \Omega^{-1} \ cm^2 \ equiv^{-1}$
