An electronic device requires two 1.50-V AA zinc-carbon batteries,which,connected in series,give 3.00 V.If the cell transfers two moles of electrons for each mole of reaction,how much electrical work can be performed by the batteries?

Question

Quizplus · Accepted Answer

The correct answer is A because the electrical work can be performed by the batteries is given by the equation W = nFE, where n is the number of moles of electrons transferred, F is the Faraday constant, and E is the cell potential. In this case, n = 2 mol, F = 96,485 C/mol, and E = 3.00 V, so W = (2 mol)(96,485 C/mol)(3.00 V) = 5.79 x 10^2 kJ.
