Calculate the resistance of an electrochemical cell given the following parameters: - The cell has a total area of 50 cm² and a separation between the electrodes of 2 cm.- The electrolyte solution has a conductivity of 2.5 × 10⁻⁴ S/cm and a temperature of 25°C.- The electrode on the left side of the cell is made of platinum and has a surface area of 25 cm². The electrode on the right side is made of silver and has a surface area of 25 cm².- The distance between each electrode and the solution is 0.5 cm.

Calculate the reaction quotient, Qc, for the reaction: 2 NO2 (g) + Cl2 (g) ⇌ 2 NO2Cl (g)At a certain temperature, the concentrations were found to be: [NO2] = 0.15 M, [Cl2] = 0.20 M, and [NO2Cl] = 0.10 M.Is the reaction at equilibrium? If not, which direction would the reaction proceed to reach equilibrium?
