Which graph correctly correlates E_(cell) as a funcation of concentrations for the cell (for different values of M and M' )? Zn(s) + Cu^(2+) (M) rarr Zn^(2+) (M') + Cu(s), E_(cell)^(@) = 1.10 V X -axis : (log_(10)[Zn^(2+)])/([Cu^(2+)]) Y-axis : E_("cell")

The cell , Zn | Zn^(2+) (1M) || Cu^(2+) (1M) Cu (E_("cell")^@ = 1. 10 V) , Was allowed to be completely discharfed at 298 K . The relative concentration of 2+ to Cu^(2+) [(Zn^(2=))/(Cu^(2+))] is :

The cell, Zn | Zn^(2+) (1M) || (1M) | Cu (E_(cell)^(@) = 1.10V) , was was allowed to be completely discharged at 298 K. The concentration of Zn^(2+) rightarrow CU^(2+)([([Zn^(2+)]/([Cu^(2+)])]) is :

For the redox reaction: Zn(s) +Cu^(2+) (0.1M) rarr Zn^(2+) (1M)+Cu(s) taking place in a cell, E_(cell)^(@) is 1.10 volt. E_(cell) for the cell will be (2.303 (RT)/(F) = 0l.0591)

Which graph correctly correlates E_("cell") as a function of concentration for the cell (for different values of M nad M' Zn(s)+Cu^(2+)(M)rarrZn^(2+(M')+Cu(s), E_("cell")^(@)=1.10V X - axis : log_(10).([Zn^(2+)])/([Cu^(2+)]), Y - axis : E_("cell")
