1.	The concentration of potassium ions inside a biological cell is least twenty time higher than the outside. The resulting potential difference across the cell is important in several processes such as transmission 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,0.05" molar")\|\|M^(+)(aq,1" molar")\|M_((s))` For the above electrolytic cell the magnitude of the cell potential `\|E_(cell)\|=70mV`. Q. For the above cellA. `E_(cell) lt 0, DeltaG gt 0`B. `E_(cell) gt 0,DeltaG lt 0`C. `E_(cell) lt 0, DeltaG^(@) gt 0`D. `E_(cell) gt 0, DeltaG^(@) lt 0`
Answer» Correct Answer - B `E_(cell)=0-(2.303RT)/(F)"log"(0.05)/(1)` =a positive value =70mV Hence `DeltaG lt 0`. [given]
