What is the Nernst equation for a cell at 298 K with E° = 0.77 V and [Zn²⁺] = 0.01 M?

What is the Nernst equation for a cell at 298 K with E° = 0.77 V and [Zn²⁺] = 0.01 M?

Step 1: Identify the Nernst equation, which is E = E° - (0.0591/n) log(Q).
Step 2: Determine the standard cell potential (E°), which is given as 0.77 V.
Step 3: Identify the number of electrons transferred in the reaction (n). For zinc (Zn), n = 2.
Step 4: Calculate the reaction quotient (Q). Since we have [Zn²⁺] = 0.01 M, Q = [Zn²⁺] = 0.01.
Step 5: Plug the values into the Nernst equation: E = 0.77 V - (0.0591/2) log(0.01).
Step 6: Calculate log(0.01), which is -2.
Step 7: Substitute log(0.01) into the equation: E = 0.77 V - (0.0591/2) * (-2).
Step 8: Calculate (0.0591/2) * (-2) = -0.0591.
Step 9: Finally, calculate E = 0.77 V + 0.0591 = 0.8291 V.
