Alcohol is removed from the bloodstream by a series of metabolic reactions. The first reaction produces acetaldehyde; then other products are formed. The following data have been determined for the rate at which alcohol is removed from the blood of an average male, although individual rates can vary by 25−30%. Women metabolize alcohol a little more slowly than men: [C 2 H 5 OH]( M ) 4.4 × 10 − 2 3.3 × 10 − 2 2.2 × 10 − 2 Rate(moI/L/h) 2.0 × 10 − 2 2.0 × 10 − 2 2.0 × 10 − 2 Determine the rate equation, the rate constant, and the overall order for this reaction.

Two cations that exchange an electron in an interface, the exchange density is worth 1.39 mA/cm2 and the current density is worth 15 mA/cm2 at 25°C. If the overvoltage is 0.14 V, calculate the reaction rate and symmetry factor. Data: R = 8,314 J mol-1 k-1: F = 96500 C
With the help of the Tafel line, it is estimated that the interchange density of the VO2+/VO2+ system on the carbon paper has a value of 3 mA cm-2. Calculate a) the current density if the voltage has a value of 1.6 mV and the temperature is 25°C. b) the beta value of the anódico process if the Tafel pendulum is 0.6 V at 25°C. Data: R = 8.314 JK-1mol-1, y F = 96485 C mol-1.
