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.
