What else can I help you with?
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?
spontaneous redox reaction

How can one determine if a redox reaction will be non-spontaneous?
The reduction potential plus oxidation potential is negative.

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 browning banana a redox reaction?
A browning banana is a redox reaction.
How can one identify a redox reaction?
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
How can a galvanic cell become an electrolytic?
the redox reaction is reserved
