Calculate standard free energy change for the reaction 2 A g + 2 H + → H 2 + 2 A g + Given: E A g + / A g o = + 0.80 V

Question

Calculate standard free energy change for the reaction 2 A g + 2 H + → H 2 + 2 A g + Given: E A g + / A g o = + 0.80 V, -308.08 kJ, 154.4 kJ, 77.2 kJ, - 154.4 kJ

MARKS App · Accepted Answer

E c e l l o = E H 2 o - E A g o = 0 - 0.80 = - 0.80 Δ G ° = - n F E c e l l o = - 2 × 96500 × ( - 0.8 ) = + 154.4 kJ
