Calculate the extent of polarization for a cell in which a copper electrode is coupled with a silver electrode at 25°C. The copper electrode has a potential of -0.34 V and the silver electrode has a potential of 0.80 V. The initial concentration of copper ions and silver ions in the solution are 0.001 M and 0.01 M, respectively. The total resistance of the cell (including both the electrolyte and the external circuit) is 10 ohms. Assume that the transfer coefficient for both the copper and silver ions is 0.5, and the Faraday constant is 96,485 C/mol.

A student wants to determine the rate law for the reaction between compound A and compound B. The student measures the initial rate of the reaction under different conditions and records the following data:| Experiment | [A] (M) | [B] (M) | Initial Rate (M/s) ||------------|---------|---------|-------------------|| 1 | 0.1 | 0.1 | 4.22x10^-4 || 2 | 0.2 | 0.1 | 8.44x10^-4 || 3 | 0.1 | 0.2 | 1.69x10^-3 |What is the rate law expression for this reaction in terms of the rate constant, k?
