Voltage is the measure of the potential difference between two substances involved in a redox reaction. It is the force that drives the transfer of electrons from one substance to another.
Voltage is calculated by subtracting the reduction potential of the substance being reduced from the oxidation potential of the substance being oxidized. This value is typically represented in volts (V).
Yes, the voltage of a redox reaction can be negative if the reduction potential is greater than the oxidation potential. This indicates that the reaction is not spontaneous and will not occur without an external source of energy.
Temperature can affect the voltage of a redox reaction by altering the kinetic energy of the particles involved. As temperature increases, the particles move faster and the reaction rate increases, resulting in a higher voltage.
The voltage of a redox reaction can be influenced by factors such as temperature, concentration of reactants, pressure, and the presence of catalysts. These factors can alter the rate of the reaction, and therefore, affect the voltage measurement.
