To calculate the Faraday constant, we need to first determine the number of moles of electrons transferred during the electrolysis process. Potassium dichromate K2Cr2O7 undergoes reduction during electrolysis as follows:Cr2O7^2- + 14H^+ + 6e^- 2Cr^3+ + 7H2OFrom the balanced equation, we can see that 6 moles of electrons are required to reduce 1 mole of Cr2O7^2- ions.Since we have 0.5 moles of potassium dichromate in the solution, the number of moles of electrons required for the reduction is:0.5 moles K2Cr2O7 * 6 moles e^- / 1 mole Cr2O7^2- = 3 moles e^-Next, we need to determine the total charge passed during the electrolysis process. We are given the current 1.5 Amperes and the time 30 minutes . We can convert the time to seconds and then calculate the total charge:30 minutes * 60 seconds / 1 minute = 1800 secondsTotal charge Q = Current I * Time t Q = 1.5 A * 1800 s = 2700 CoulombsNow, we can calculate the Faraday constant F using the total charge Q and the number of moles of electrons n :F = Q / nF = 2700 C / 3 moles e^-F 900 C/mol e^-The calculated value of the Faraday constant is approximately 900 Coulombs per mole of electrons. The actual Faraday constant is around 96485 C/mol e^-, so our calculated value is not accurate. This discrepancy could be due to experimental errors or assumptions made during the calculation.
