Question

The value of E°_cell for the reaction 2Cr³⁺(aq) + 6Hg(l) $\to$ 2Cr(s) + 3Hg₂²⁺(aq) Is 1.59 V. Calculate $\Delta$G°for the reaction.

Quizplus · Accepted Answer

The correct answer is A: -921 kJ.The relationship between the standard cell potential (E°cell) and the standard free energy change (ΔG°) is given by the equation:ΔG° = -nFE°cellwhere n is the number of moles of electrons transferred in the reaction and F is the Faraday constant (96,485 C/mol).In this case, n = 6 (since 6 electrons are transferred in the reaction) and E°cell = 1.59 V. Substituting these values into the equation, we get:ΔG° = -6 × 96,485 C/mol × 1.59 V = -921 kJ/molTherefore, the standard free energy change for the reaction is -921 kJ.
