For the electrochemical cell,

M\left| {{M^ + }||{X^ - }} \right|X,

{E^ \circ }({M^ + }|M) = 0.44V,{E^ \circ } = (X|{X^ - }) = 0.33V

. From this data one can deduce that

View answer and explanation

Correct option: B

{M^ + } + {X^ - } \to M + X

is the spontaneous reaction

Option C (

M + X \to {M^ + } + {X^ - }

is the spontaneous reaction) is correct because the cell potential is positive, indicating a spontaneous reaction in the direction written.
