Q-13. Which of the presented below formulas don't present the Nernst equation? a) Ecell = Ecell RT/nF (In Q); b) Ecell = Ecell- 0.0592/n (log [Me*]; b) Ecell = - 0.0592/n log (diluted solution)/(concentrated solution); d) there is no correct answer Q-14. Predict the cell reaction, standard cell potential of a galvanic cell (E) and free Gibbs energy (AG) for the following half cells. The concentration of all ions is equal to 1 M, F = 96500 C/mole NIO2(s) + 2 H20 + 2e > Ni(OH)2 + 20H (aq) ENIO2 = 0.49 V Fe(OH)2(s) + 2 e Fe(s) + 20H(aq) EFe(OH)2 = -0.89 V
