AIIMS 2010 Chemistry Cell Potentials MCQ Question
For the electrochemical cell, M | M⁺ || X⁻ | X, E°(M⁺/M) = 0.44 V and E°(X/X⁻) = 0.33 V. From this data one can deduce that
M + X⁻ → M⁺ + X⁻ is the spontaneous reaction
M⁺ + X⁻ → M + X is the spontaneous reaction
Ecell = 0.77 V
Ecell = -0.77 V
Correct Answer
Detailed Explanation
M + Y -> M + X is spontaneous because for the cell represented by M|M+ || X|X, the value of E° is positive i.e. (0.44 - 0.33) V = 0.11 V.
