A) \[E{{{}^\circ }_{cell}}=-0.77\,V\]
B) \[{{M}^{+}}+{{X}^{-}}\to M+X\] is the spontaneous reaction
C) \[M+X\to {{M}^{+}}+{{X}^{-}}\]is the spontaneous reaction
D) \[E{{{}^\circ }_{cell}}=.77\ V\]
Correct Answer: B
Solution :
For \[{{M}^{+}}+{{X}^{-}}\to M+X\] \[E_{Cell}^{0}=E_{Cathode}^{0}+E_{Anode}^{0}\]\[=0.44-0.33=+0.11\ V\] Since \[E_{Cell}^{0}=(+)\ 0.11\ V\] is positive hence this reaction should be spontaneous.You need to login to perform this action.
