Question

Question

If the equilibrium constant for a two electron redox reaction at 198 °C is 1500, calculate the ΔG° and E⁰red.

Answer 1

Answer #1

The value of Gibbs free energy is given by :

∆G = - RT ln K

Where ∆G = Gibbs free energy

T = Temperature in Kelvin

R = gas constant

K = equilibrium constant.

The relation between ∆G and reduction potential is given by :

∆G = - nFE

Using the above relation the value of both the unknowns can be calculated .

The problem is solved in the picture attached below :

Given, T 198°C 198 + 273.471k 1500 Equilibidium constant, OGO nFE & AG - RJ Ink AG 8.314 Xu71 en 1500 - 28, 637.8 AJ As AGO

Hope you will find the answer helpful.please rate .kind regards :) :)
