Sure! Here's a precise problem:Calculate the cell potential for the following electrochemical reaction: Fe(s) + Cu2+(aq) → Fe2+(aq) + Cu(s) Assume that the concentrations of Fe2+(aq) and Cu2+(aq) are both 1.00 M and the temperature is 25°C.

To calculate the cell potential for the given electrochemical reaction, we need to use the Nernst equation. First, we need to find the standard reduction potentials for both half-reactions:1. Fe2+ aq  + 2e-  Fe s   E = -0.44 V  reduction 2. Cu2+ aq  + 2e-  Cu s   E = +0.34 V  reduction Since Fe is being oxidized and Cu2+ is being reduced, we need to reverse the first half-reaction:1. Fe s   Fe2+ aq  + 2e-  E = +0.44 V  oxidation Now, we can add the two half-reactions to get the overall reaction:Fe s  + Cu2+ aq   Fe2+ aq  + Cu s Next, we can calculate the standard cell potential  Ecell  by subtracting the standard potential of the oxidation half-reaction from the standard potential of the reduction half-reaction:Ecell = E reduction  - E oxidation  = 0.34 V - 0.44 V = -0.10 VSince the concentrations of Fe2+ aq  and Cu2+ aq  are both 1.00 M, the reaction quotient  Q  is equal to 1:Q = [Fe2+]/[Cu2+] = 1.00/1.00 = 1Now, we can use the Nernst equation to calculate the cell potential at 25C:Ecell = Ecell -  RT/nF  * ln Q where:R = 8.314 J/ molK   gas constant T = 25C + 273.15 = 298.15 K  temperature in Kelvin n = 2  number of electrons transferred F = 96485 C/mol  Faraday's constant Ecell = -0.10 V -   8.314 J/ molK  * 298.15 K  /  2 * 96485 C/mol   * ln 1 Since ln 1  = 0, the last term in the equation becomes 0:Ecell = -0.10 VSo, the cell potential for the given electrochemical reaction is -0.10 V.
