If the potential of a voltaic cell is +0.837 V, what is the free-energy change when two moles of electrons are transferred in the oxidation-reduction reaction?

Question

Quizplus · Accepted Answer

The free-energy change (ΔG) is calculated using the formula ΔG = -nFE, where n is the number of moles of electrons transferred (2 moles), F is Faraday's constant (approximately 96485 C/mol), and E is the cell potential (0.837 V). Plugging in these values gives ΔG = -(2)(96485)(0.837) = -161.5 kJ, which is approximately -162 kJ.
