Use the provided reduction potentials to calculate Δ_rG° for the following balanced redox reaction: Pb²⁺(aq) + Cu(s) → Pb(s) + Cu²⁺(aq)
E°(Pb²⁺/Pb) = -0.13 V and E°(Cu²⁺/Cu) = +0.34 V

Question

Quizplus · Accepted Answer

To find ΔrG°, use the formula ΔrG° = -nFE°, where n is the number of moles of electrons transferred, F is Faraday's constant (96,485 C/mol), and E° is the standard cell potential. The cell potential E° = E°(cathode) - E°(anode) = -0.13 V - 0.34 V = -0.47 V. Since 2 electrons are transferred, ΔrG° = -2 * 96,485 * (-0.47) = +91 kJ/mol.
