An electronic device requires four 1.50-V AA alkaline batteries, which, connected in series, give 6.00 V.If the cell transfers two moles of electrons for each mole of reaction, what is the Gibbs free-energy change for the redox reaction in each of the batteries?

Question

Quizplus · Accepted Answer

The Gibbs free-energy change (ΔG) can be calculated using the formula ΔG = -nFE, where n is the number of moles of electrons, F is Faraday's constant (approximately 96485 C/mol), and E is the cell potential. For one battery, E = 1.50 V, and n = 2 moles of electrons. Thus, ΔG = -2 * 96485 * 1.50 = -2.90 * 10^2 kJ.
