What must be the sign of the standard cell potential (cell) for a redox reaction to be spontaneous?
For a redox reaction to be spontaneous, the standard cell potential (cell) must be positive.
What can be said about a redox reaction that has a positive potential?
. The reaction will be spontaneous.
What redox conditions will produce a spontaneous reaction?
The sum of the voltages of the half-reactions is positive.
What will form a spontaneous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
What is the reaction in a fuel cell spontaneous and non spontaneous?
Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.
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?

What must be the sign of the standard cell potential (cell) for a redox reaction to be spontaneous?
For a redox reaction to be spontaneous, the standard cell potential (cell) must be positive.
What property characterizes a spontaneous red ox reaction?
A spontaneous redox reaction is characterized by a negative Gibbs free energy change (ΔG < 0), indicating that the reaction can occur without external energy input. Additionally, it often involves the transfer of electrons between reactants, leading to changes in oxidation states. Spontaneity can also be assessed through the electromotive force (EMF) of the reaction, where a positive cell potential (E) suggests that the reaction is favorable.

How can one determine if a redox reaction will be non-spontaneous?
The reduction potential plus oxidation potential is negative.
What property characteristics a spontaneous redox reaction?
A spontaneous redox reaction is characterized by a negative Gibbs free energy change (ΔG < 0), indicating that the reaction can occur without external energy input. Additionally, it typically has a positive cell potential (E°) in electrochemical terms, reflecting a favorable driving force for electron transfer. The reaction also involves the simultaneous oxidation and reduction of species, where one substance loses electrons (oxidation) while another gains them (reduction).
What forms a spontaneous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
What identifies a spontaneous redox reaction?
A spontaneous redox reaction is identified by a positive cell potential (E°) when measured under standard conditions, indicating that the reaction can occur without external energy input. This is often determined using the standard reduction potentials of the half-reactions involved; if the total cell potential is positive, the reaction is spontaneous. Additionally, spontaneity can be inferred from the Gibbs free energy change (ΔG), where a negative ΔG signifies that the reaction is thermodynamically favorable.
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.
When is a red-ox reaction spontaneous?
A redox reaction is spontaneous when the overall change in Gibbs free energy (ΔG) is negative. This typically occurs when the standard electrode potentials of the half-reactions involved indicate a favorable direction for electron flow, resulting in a positive cell potential (E°). In simpler terms, a spontaneous redox reaction can occur without external energy input, driven by the inherent chemical properties of the reactants.
