mix A A xa 8. Show that for regular solutions the Gibbs energy of mixing is A G=nRT{x, Inxa +(1-x2) ln(1 – xx)} + nĒRTXA (1-x2) where XA is the mole fraction of A component and is a dimensionless parameter. Also show that 2u - Uaa - u ६ where Ujj denotes T the intermolecular interaction between molecules i and j. Ex(20.3 АВ AA BB
= - = 1. (20 pts) Given that AGº = -212.7 kJ/mol for the reaction in the Daniell cell at 25°C, and b(CuSO4) = 1.0 x 10-3 mol/kg and (ZnSO4) = 3.0 x 10-3 mol/kg. Calculate (a) the ionic strengths of the solutions, (b) the mean ionic activity coefficients in the compartments, (c) the reaction quotient, (d) the standard cell potential, and (e) the cell potential. (Take Y+ = 7= y.) y Y- ) = =
