When a rotating disk electrode (RDE) is held at a high enough potential, the rate of the reaction is governed by the diffusion rate, the rate at which the analyte diffuses through the diffusion layer to the electrode. The thickness of this diffusion layer, 8, is calculated as 8 = 1.61 D¹36-1/21/6 where D is the diffusion coefficient (m²/s), v is the kinematic viscosity of the liquid (m²/s), and is the rotation rate (radians/s) of the electrode. Additionally, the current density, J (A/m²), is measured using the Levich equation, J = 0.62nFD2/3¹/2-1/6 Co where n is the number of electrons transferred in the half-reaction, F is the Faraday constant, and Co is the concentration of the electroactive species (mol/m³). Calculate 8, in micrometers, and the current density, J, for the reduction of 0.020 M T1³+ to Tl* at a gold electrode in 1 F HCl at 0.80 V vs. SHE at 2300 rpm, where D = 2.5 x 10-9 m²/s and v= 2.0 x 10-6 m²/s. 8= μm

Please help solve this question, will provide thumbs up if correct, Thank you.   

When a rotating disk electrode (RDE) is held at a high enough potential, the rate of the reaction is governed by the diffusion rate, the rate at which the analyte diffuses through the diffusion layer to the electrode. The thickness of this diffusion layer, 8, is calculated as 8 = 1.61 D¹/3-1/2,1/6 where D is the diffusion coefficient (m²/s), v is the kinematic viscosity of the liquid (m²/s), and wo is the rotation rate (radians/s) of the electrode. Additionally, the current density, J (A/m²), is measured using the Levich equation, J = 0.62nFD2/3¹/2-1/6 Co where n is the number of electrons transferred in the half-reaction, F is the Faraday constant, and Co is the concentration of the electroactive species (mol/m³). Calculate 8, in micrometers, and the current density, J, for the reduction of 0.020 M T1³+ to Tl* at a gold electrode in 1 F HCl at 0.80 V vs. SHE at 2300 rpm, where D = 2.5 × 10-⁹ m²/s and v = 2.0 × 10-6 m²/s. 8 = μm
