1.	For the electrochemical cell, `(M\|M^(o+))\|\|(X^(c-)\|X)`, `E^(c-)._((M^(o+)\|M))=0.44V`, and `E^(c-)._((X\|X^(c-))=-0.33V`. From this data, one can conclude thatA. `M + X rarr M^+ +X^-`is the spontaneous reactionB. `M + X rarr M^+ +X^-` is the spontaneous reactionC. `E_(cell)^@ =0.. 77 V`D. ` E_(cell)^@ =0.. 77 V`
Answer» Correct Answer - B For the give cell `M\|M^+ \|\|X^_\|X, ` the cell reaction is derived as follows : RHS : reduction `X+e^- rarr X^-` …(i) LHS : Oxdation ` M rarr M^+ +e^-` …(ii) Add (i) and (ii) `M+X rarr M^+ +X^-` The cell potential `=- 0. 11 V` Since `E_(cell) =- ve`, the cell reaction derived above is not spontaneous . In fact , the reverse reaction will occur spontaneously.
