- Topic: Photochemistry and Photophysics of Supramoleculesarrow_forwardTwo 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 Carrow_forwardWith 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.arrow_forward
- Hi can you please help me solve this problem? thank youarrow_forwardAn electrode process takes place at a metal-solution interface. Indicate the current condition that must be met for Faradaic rectification to occur.arrow_forwardAt a metal-solution interface, an electron is exchanged, and the symmetry factor beta < 0.5 is found in the Butler-Volmer equation. What does this indicate?arrow_forward
