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) is 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 (6.00 V for the series connection). For two moles of electrons, ΔG = -2 * 96485 * 6.00 = -1157820 J or -1157.82 kJ, which is approximately -2.90 x 10^2 kJ.
