Correct. Since they require energy, they won't happen spontaneously.
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.
They are nonspontaneous
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
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.
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
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.

There was one reaction that is used for electroplate. The one thing used is copper. A nonspontaneous redox reaction
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.
They are nonspontaneous
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
The reverse reaction is endothermic and nonspontaneous.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
A high temperature can make a nonspontaneous reaction spontaneous by providing enough energy to overcome the activation energy barrier, allowing the reaction to proceed. At low temperatures, the kinetic energy of the molecules may not be sufficient for them to react, but increasing the temperature can provide the necessary energy for the reaction to occur spontaneously.
-2.37 - 0.34
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.
