Utilizing data to compute the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is 0.0002 molar as well as everything else is standard use 298 K for the temperature, R = 8.314 J/mol-K, and F = 96,485 C/mol:
(a) 1 Fe2+(aq) + 1 Ni(s) --> 1 Fe(s) + 1 Ni2+(aq) E =____ V(b) 1 Br2(l) + 1 Cd(s) --> 2 Br-(aq) + 1 Cd2+(aq) E =_____ V(c) 2 Fe(CN6)3-(aq) + 2 Cl-(aq) --> 2 Fe(CN6)4-(aq) + 1 Cl2(g) E =____ V(d) 1 F2(g) + 1 Hg22+(aq) --> 2 F-(aq) + 2 Hg2+(aq) E = ____ V
