The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
The overall voltage for the nonspontaneous redox reaction involving magnesium (Mg) and copper (Cu) can be determined using standard reduction potentials. The reduction potential for Cu²⁺ to Cu is +0.34 V, while the oxidation potential for Mg to Mg²⁺ is -2.37 V. The overall cell potential (E°cell) is calculated by adding the reduction potential of the cathode (Cu) to the oxidation potential of the anode (Mg), resulting in E°cell = 0.34 V - 2.37 V = -2.03 V. Since the value is negative, the reaction is nonspontaneous under standard conditions.
They are nonspontaneous
In the nonspontaneous redox reaction involving magnesium (Mg) and copper ions (Cu²⁺), magnesium acts as the reducing agent, while copper ions are reduced to copper metal. The standard reduction potential for Cu²⁺/Cu is +0.34 V, and for Mg²⁺/Mg, it is -2.37 V. The overall cell potential (E°) can be calculated as E° = E°(reduction) - E°(oxidation), which yields E° = 0.34 V - (-2.37 V) = 2.71 V. Since the reaction is nonspontaneous, the cell potential would be negative under standard conditions.

There was one reaction that is used for electroplate. The one thing used is copper. A nonspontaneous redox reaction
A nonspontaneous redox reaction is driven by an external source of electrical energy, such as a battery, when a current passes through the electrolytic cell. In an electrolytic cell, the anode is positive and the cathode is negative; electrons flow from the anode to the cathode, and oxidation occurs at the anode while reduction occurs at the cathode.

A nonspontaneous process is a reaction or change that does not occur naturally under given conditions and requires an input of energy to proceed. Unlike spontaneous processes, which occur without external energy, nonspontaneous processes need external intervention, such as heat or work, to drive them forward. Examples include the electrolysis of water and the synthesis of glucose in photosynthesis.
•Redox reactions can cause a change in volume •2Fe + 1.5 O2 > Fe2O3
In the nonspontaneous redox reaction involving magnesium (Mg) and copper (Cu), the overall voltage (or electromotive force, EMF) can be determined using standard reduction potentials. The standard reduction potential for Cu²⁺/Cu is +0.34 V, while for Mg²⁺/Mg it is -2.37 V. The overall voltage for the reaction, calculated by subtracting the reduction potential of magnesium from that of copper, is approximately +2.73 V. However, since the reaction is nonspontaneous, the voltage indicates that an external energy source is required to drive the reaction.
