How can one determine if a redox reaction will be non-spontaneous?
The reduction potential plus oxidation potential is negative.
What forms a spontaneous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
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.
What conditions will cause a redox reaction to be no spontaneous?
A redox reaction will not be spontaneous if the standard cell potential (E°) is negative, indicating that the reaction favors the reactants rather than the products. Additionally, high activation energy barriers, unfavorable temperature conditions, or the presence of competing reactions can also hinder spontaneity. In such cases, external energy input may be required to drive the reaction forward.
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
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 property characterizes a spontaneous redox reaction?
A positive sum of the two half-reactions' standard potentials
What redox conditions will produce a spontaneous reaction?
The sum of the voltages of the half-reactions is positive.

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.
Is browning banana a redox reaction?
A browning banana is a redox reaction.
What identifies an oxidation-reduction reaction'?
An oxidation-reduction (redox) reaction involves the transfer of electrons between reactants. The substance that loses electrons is oxidized, while the substance that gains electrons is reduced. Redox reactions result in changes in oxidation states of atoms involved.
