Correct. Since they require energy, they won't happen spontaneously.
They are nonspontaneous
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
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
An electrolytic cell
Electrodeposition/electrolysis are the chemical reactions involved in electroplating.
There was one reaction that is used for electroplate. The one thing used is copper. A nonspontaneous redox reaction
Electrolytic cell
entropy and energy
They are nonspontaneous
The reverse reaction is endothermic and nonspontaneous.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
-2.37 - 0.34
The reverse reaction is exothermic and spontaneous.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
When H and S are both positive
The reverse reaction is endothermic and spontaneous.
nonspontaneous
