Calculate Δ_rG° for the Disproportionation Reaction of Copper(I)ion (Cu⁺)at 25

question 1

Multiple Choice

Calculate Δ_rG° for the disproportionation reaction of copper(I) ion (Cu⁺) at 25 °C. 2 Cu⁺(aq) → Cu²⁺(aq) + Cu(s)
The standard reduction potentials are as follows:
Cu⁺(aq) + e^- → Cu(s)
E° = +0.518 V
Cu²⁺(aq) + 2 e^- → Cu(s)
E° = +0.337 V

• A) -165 kJ/mol⋅rxn
• B) -135 kJ/mol⋅rxn
• C) -34.9 kJ/mol⋅rxn
• D) +17.5 kJ/mol⋅rxn
• E) +135 kJ/mol⋅rxn
