Question

In order to derive a simplified version of the Nernst equation by assuming standard temperature we can substitute which of the following into the general equation?

a. Faraday's constant
b. Standard pressure (1 atm)
c. 298 K
d. 25 °C

Answer 1

c. 298 K

Step-by-step explanation:

Nernst equation is an equation used in electrochemistry that relates the reduction potential of a reaction with the standard potential, temperature and concentrations of the reactants in that are been reducted and oxidized. The formula is:

E = E° - RT / nF ln [Red] / [Ox]

Where R is gas constant (8.314J/molK), T is absolute temperature (In Kelvin), n are moles of electrons and F is faraday constant (K/Volt*mol)

In electrochemistry, standard temperature is taken as 298K. That means by assuming standard temperature we can substitute T as:

c. 298 K
