In a fuel cell, the overall redox reaction is spontaneous, meaning it proceeds on its own without an external power source. The electrode reactions that occur at the anode and cathode are also spontaneous, as they involve the transfer of electrons from the fuel to the oxidant. This spontaneous reaction generates electrical energy that can be used to power devices.

What is the voltage for the non spontaneous reaction between silver Ag and copper Cu and their ions?
The standard cell potential for the non-spontaneous reaction between silver and copper ions (Ag+ and Cu2+) is determined by subtracting the reduction potential of Ag+ from that of Cu2+. The cell potential would be negative as the reaction is non-spontaneous, indicating that an external voltage larger than the calculated value would be needed to drive the reaction in the reverse direction.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
How does an electrolytic cell work simple answer?
An electrolytic cell uses an external power source to drive a non-spontaneous chemical reaction. Electricity is used to force electrons through the cell, causing a redox reaction to occur at the electrodes. This allows for the production of new chemical compounds or the separation of substances.
What energy transformation occurs in an electrolytic cell?
In an electrolytic cell, electrical energy is transformed into chemical energy. This occurs when an external voltage is applied to drive a non-spontaneous redox reaction to produce a desired chemical product.
How can you reverse a redox reaction in a voltaic cell?
To reverse a redox reaction in a voltaic cell, you would need to apply an external voltage that opposes the direction of electron flow. This process is known as electrolysis, where an external power source drives the non-spontaneous reaction. By applying a voltage higher than the cell potential, you can force the reaction to run in the reverse direction.
Which best describes a galvanic cell a battery containing a non spontaneous reaction a battery containing an acid and a base a battery containing a spontaneous redox reaction a battery that requires?
spontaneous redox reaction

How can a galvanic cell become electrolytic cell?
A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
What is a non spontaneous 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
An electrolytic cell is different from a voltaic cell because in an electrolytic cell?
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
Is candle burning a spontaneous or non spontaneous reaction?
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
What kind of cell has non spontaneous voltage?
Electrolytic cell
Ask us anythingWhich of the following describes a nonspontaneous 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
How is an electolytic cell different from a galvantic cell?
In an electrolytic cell, electrical energy is used to drive a non-spontaneous reaction, causing a chemical change. In contrast, a galvanic cell generates electrical energy from a spontaneous chemical reaction. Electrolytic cells are often used in processes like electrolysis, while galvanic cells are used in batteries.
Forming a triacylglyceride from three fatty acids and glycerol...identify this reaction as either anabolic or catabolic endergonic or exergonic and spontaneous or non spontaneous.?
Forming a triacylglyceride from three fatty acids and glycerol is an anabolic reaction that is endergonic (requires energy input) and non-spontaneous under normal cellular conditions.
How do you determine whether a reaction is spontaneous or non spontaneous?
A reaction is spontaneous if the Gibbs free energy change (ΔG) is negative. This means that the reaction can proceed without external energy input. In contrast, a reaction is nonspontaneous if ΔG is positive, meaning external energy is needed for the reaction to occur.
