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.
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.

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
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
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.

The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.

No, a catalyst alone cannot make a nonspontaneous reaction occur spontaneously. A catalyst can only speed up the rate of a reaction by lowering the activation energy, but it cannot change the overall thermodynamics of the reaction. In order for a nonspontaneous reaction to occur spontaneously, the reaction must have a negative change in Gibbs free energy (G) value.
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
