Answer to Question #104133 in General Chemistry for James Okike

Question

CO/CO2+//Ni2+/Ni
Calculate the cell potential and energy

Answer 1

$CO + H_2O \to CO_2 + 2H^+ + 2e^-$ $E_o=0.53V$

$Ni^{2+} + 2e^- \to Ni$ $E_o=-0.25V$

$\therefore E_{cell}=0.53-0.25=0.28V$

$\Delta G=-nEF=-2*0.08*96500=-15.44kJ$ (Answer)
