The standard cell potential (E°_cell)of the reaction below is +0.126 V. The value of ΔG° for the reaction is ________ kJ/mol. Pb (s) + 2H⁺(aq) → Pb²⁺ (aq) + H₂ (g) A)-24.3 B)+24.3 C)-12.6 D)+12.6 E)-50.8

Question

Quizplus · Accepted Answer

The relationship between ΔG° and E°cell is given by the equation ΔG° = -nFE°cell, where n is the number of moles of electrons transferred (2 in this case), F is Faraday's constant (96485 C/mol), and E°cell is the standard cell potential. Plugging in the values: ΔG° = -(2)(96485)(0.126) = -24.3 kJ/mol.

The Standard Cell Potential (E°cell)of the Reaction Below Is +0
