Question

All the energy released from the reaction X → Y , Δ r G o = - 193 kJ mo l - 1 is used for oxidizing M + as M + → M 3 + + 2 e - , E o = - 0.25 V . Under standard conditions, the number of moles of M + oxidized when one mole of X is converted to Y is [F = 96500 C m o l - 1 ]

Quantrex Academy · Accepted Answer

Correct answer: 4

Δ G o = - n F E o - n = 193 × 1 0 3 96500 × 0.25 = 8 So No. of moles of M + oxidized by 1 moles of X = 8 2 = 4

All the energy released from the reaction X → Y , Δ r G o = - 193 kJ mo l - 1 is used for oxidizing M + as M + → M 3 + + 2 e - , E o = - 0.25 V . Under standard conditions, the number of moles of M + oxidized when one mole of X is converted to Y is [F = 96500 C m o l - 1 ]
