Which graph correctly correlates Ecell as a function of concentrations for the cell (for different values of M and M1) ?Zns+Cu2+M→Zn2+M'+Cus;   E0cell=1.10 V, Ecell is on x-axis and log10Zn2+Cu2+ is on y - axis.

Given reaction;Zns+Cu2+M→Zn2+M'+Cus,E0cell=1.10 VEcell  is on x− axis and log10⁡Zn2+Cu2+ is on y - axis Applying nernest equationEcell=Ecell0−0.059nlogOSRSWhere, E=  Potential of electrodeE°= Standard Potential[OS] =  Concentration of Oxidation state[RS] = Concentration of Reduction stateEcell=Ecell0−0.0592log⁡zn2+Cu2+(∵n=2)⇒logzn2+Cu2+=    −20.059Ecell+Ecell0⇒logZn2+Cu2+=−20.059Ecell+1.1
