An electrolytic cell
They are nonspontaneous
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.
True. When you take the reverse reaction of a spontaneous process, it typically requires an input of energy and is considered a nonspontaneous process. Spontaneous processes occur naturally without external energy, while nonspontaneous processes do not occur without energy being supplied.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
An electrolytic cell
They are nonspontaneous
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 sum of the voltages of the oxidatiin and reduction half-reactions is negative.

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.
The energy graph that represents the nonspontaneous transition is the one that shows an increase in energy over time, indicating that energy input is required for the transition to occur.
True. When you take the reverse reaction of a spontaneous process, it typically requires an input of energy and is considered a nonspontaneous process. Spontaneous processes occur naturally without external energy, while nonspontaneous processes do not occur without energy being supplied.
There was one reaction that is used for electroplate. The one thing used is copper. A nonspontaneous redox reaction
