The cytochromes are heme‑containing proteins that function as electron carriers in the mitochondria. Calculate the difference in the reduction potential (ΔE∘′) and the change in the standard free energy (ΔG∘′) when the electron flow is from the carrier with the lower reduction potential to the higher. cytochrome c1 (Fe3+)+e−↽−−⇀cytochrome c1 (Fe2+)E∘′=0.22 V cytochrome c (Fe3+)+e−↽−−⇀cytochrome c (Fe2+)E∘′=0.254 V Calculate ΔE∘′ and ΔG∘′ .

Complete Question

The change in reduction potential is  

The change in standard free energy is  

Explanation:

From the question we are told that

At the anode

      ⇔

At the cathode

      ⇔

The difference in the reduction potential is mathematically represented as

substituting values

The change in the standard free energy is mathematically represented as

Where  F is the Faraday constant with value  F = 96485 C

and  n i the number of the number of electron = 1

   So
