What is the maximum amount of electrical energy that can be obtained from one mole of Ni2O3? — Electrochemistry Chemistry Question

💡 Solution & Explanation

The maximum electrical energy obtainable corresponds to the magnitude of the standard Gibbs free energy change: $\Delta G^\circ = -nFE^\circ$. For the reaction of 1 mole of $Ni_2O_3$, $n = 2$ moles of electrons are transferred. Energy = $2 \times 96500 \text{ C/mol} \times 1.27 \text{ V} = 245,110 \text{ J} = 245.11 \text{ kJ}$.
