QUESTION 7 Given the following reaction, Cu2*(aq) + Zn(s) - Cu(s) + Zn2*(aq) E° = 1.10 V Use the Nernst equation to calculate the cell potential for the cell described with standard line notation below. Zn|Zn2*(0.5082 M)||Cu²*c0.2699 M)|Cu Units are not required. Report answer to three decimal places.

Consider the cell described below. Al | Al³+ (1.00 M) || Pb²+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al³+] to have changed by 0.45 mol/L. (Assume T= 25°C.) V Need Help? Read It Watch It

+ Cell Potential and Equilibrium The equilibrium constant, K, for a redox reaction is related to the standard potential, E, by the equation In K FE RT where 72 is the number of moles of electrons transferred, F (the Faraday constant) is equal to 96,500 C/(mol e-). R (the gas constant) is equal to 8.314 J/(mol K), and T is the Kelvin temperature.
