y=kx
4=1k
k=4
y=4x
so when x=2
y=4(2)
y=8
n=8
C is answer
The required Standard electrode potential is +1.18V.
What is Standard electrode potential?
- The difference in voltage between the cathode and anode is known as the standard cell potential. View Cell Potentials for more details. All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
- The difference between the two electrodes, known as the standard cell potential (Eocell), creates the cell's voltage.
- The equilibrium potential can be measured using the standard electrode potential.
- The potential of a cell under normal state circumstances, which are roughly represented by concentrations of 1 mole per litre, is known as the cell's standard state potential.
Given that,

0.0-(-1.18)=+1.18V
=+1.18V
The required Standard electrode potential is +1.18V.
