1. . Calculate the limiting steady state current density
for an electrode reaction with two electrons transfer from a 0.05 M
aqueous solution in the presence of excess inert electrolyte
assuming a diffusion layer thickness of 0.05 cm and diffusion
coefficient of 5.2x10-9 m2/s
2.
I. The voltage of the cell
At 25 oC is 0.4624 and 0.5792 volt when the
molality of HCl is 0.01 and 0.001 respectively. The experimental
mean activity coefficient,of the 0.01 m solution is 0.905.Find the
experimental mean activity coefficient of the 0.001 m solution.
Consider the half-cell reaction AgCl(s) + = = Ag(s) + CI+ (aq). If y(AgCl) - - 109.721 kJ/mol, and if 6° - +0.222 V for this half-cell, calculate the standard = Gibbs energy of Cl(aq).
The e.m.f. of the cell Ag|AgNO, (aq.,0-01 mol kg) AgNO, (aq.0-1 mol kg bag is 0-054 V, while that of the cell Ag/AgNO, (aq.0-01 molkg); AgNO, (aq.0-1 mol kg)| Ag is 0-058 V. If the mean ion activity coefficients of aqueous 001 and 0-10 mol kg silver nitrate are 0-898 and 0-735 respectively, obtain a mean value for the transport number of the silver ion.
