Question:

Calculate the potential for each of the voltaic cells in Exercise 18.44 when the concentrations of the soluble species and gas pressures are as follows: (a) [Fe+] = 0.050 M, [Zn+] = 1.0 10- M (b) [Fe+] = 0.20 M, [Fe+] = 0.010 M, [CI-] = 4.0 X 10-3 M (c) [Br] =

Exercise 18.44

For each of the reactions, calculate E° from the table of standard potentials, and state whether the reaction is spontaneous as written or spontaneous in the reverse direction under standard conditions. (a) Zn(s) + Fe+ (aq) Zn+ (aq) + Fe(s) (b) AgCl(s) + Fe+ (aq) Ag(s) + Fe+ (aq) + Cl (aq) (c) Br(l) +
