“Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved, then please specify the question number or post only that question.” The electrode which has less negative reduction potential will act as a cathode and will undergo reduction. However, if the reduction potential of the electrode is more negative, that electrode will act as an anode and will undergo oxidation. The given cell reaction is shown below. The standard reduction potential of Cu electrode = 0.34 V The standard reduction potential of Mg electrode = -2.37 V The standard cell potential is calculated as follows: Ecell∘=Ecathode∘-Eanode∘ =-2.37V-0.34 V =-2.71 V The importance of Gibbs energy is that it gives information about the spontaneity of the reaction or a process. The relation between standard free energy change and standard cell potential is shown below. ∆G∘=-nFE∘ Since the value of standard cell potential is comes out to be negative. Therefore, the standard free energy change will comes out to be positive, therefore, the given cell reaction is not spontaneous.
