The electrochemical cell shows below is a concentration cell. `M|M^(2+)` (saturated solution of a sparingly soluble salt, `MX_(2))||M^(2+)(0.001)" mol "dm^(-3))|M`. The emf of the cell Depends on the difference in concentration of `M^(2+)` ions at the two electrodes. the emf of the cell at 298K is 0.059V. Q. The value of `DeltaG(kJ" "mol^(-1))` for the given cell is (take `1F=96500" C "mol^(-1)`)A. `-5.7`B. `5.7`C. `11.4`D. `-11.4` |
