The concentration of potassium ions inside a biological cell is at least twenty times higher than the outside. The resulting potential differences across the cell is important in several processes such as transmision of nerve impulses and maintaining the ion balance. a simple model for such a concentration cell involving a metal M is:
`M(s)|M^(+)(aq)||M^(+)(aq,1 molar)|M(s)`
For the above the electrolytic cell the magnitude of the cell potential `|E_(cell)|=70mV`
For the above cell

Options

A. `E_(cell)<0; DeltaG>0`
B. `E_(cell)>0; DeltaG<0`
C. `E_(cell)<0; DeltaG^@>0`
D. `E_(cell)>0; DeltaG^@<0`
