Question

A cell reaction has E°cell = 0.74 V and Δr G° = -142610 J/mol at 298 K. How many electrons are transferred? (F = 96500 C/mol)

Options

Choose one · Correct answer highlighted

Explanation

Δr G° = -n F E°cell , -142610 = -n × 96500 × 0.74 . n = (142610/96500 × 0.74) = (142610/71410) ≈ 2 .
