Is the reaction spontaneous or non-spontaneous when considering the keyword "spontaneous vs non-spontaneous"?
In the context of "spontaneous vs non-spontaneous," a reaction is considered spontaneous if it occurs on its own without needing external influence. On the other hand, a non-spontaneous reaction requires external energy input to occur.
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 significance of delta G in chemical reactions?
The significance of delta G in chemical reactions is that it indicates whether a reaction is spontaneous or non-spontaneous. A negative delta G value means the reaction is spontaneous and can proceed on its own, while a positive delta G value means the reaction is non-spontaneous and requires external energy input to occur.
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.
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.
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.
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
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
Is the reaction spontaneous or non-spontaneous at 298 k?
To determine if a reaction is spontaneous or non-spontaneous at 298 K, we can use the Gibbs free energy equation, ΔG = ΔH - TΔS. If ΔG is negative, the reaction is spontaneous; if ΔG is positive, it is non-spontaneous. The values of ΔH (enthalpy change) and ΔS (entropy change) must be known to evaluate the spontaneity at this temperature. Without specific values for ΔH and ΔS, we cannot definitively conclude the spontaneity.
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.
