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 we can deduce that :
A. `M+X rarr M^(+) + X^(-)` is the spontaneous reaction
B. `M^(+) + X^(-) rarr M + X` is the spontaneous reaction
C. `E_("cell") = 0.77 V`
D. `E_("cell") = - 0.77 V`

Answer 1

Correct Answer - B
