Electrochemical Cells
Spontaneity of Reaction
100
Oxidation reduction reactions involve the transfer of these.
What are electrons?
100
The table we were given lists these types of agents on the left, and these on the right.
What are oxidizing agents, reducing agents?
100
The cell potential for a voltaic cell has a value that is this.
What is positive?
100
A reaction that moves toward equilibrium without assistance.
What is a spontaneous reaction?
200
Oxidizing agents undergo this.
What is reduction?
200
Better oxidizing agents are located here on the table
What is bottom left?
200
These are used in a voltaic cell when a redox reaction does not include metals that could be used for the anode and/or cathode.
What is an inert electrode?
200
The Gibbs free energy change for this type of reaction is greater than zero
What is non-spontaneous?
300
This readily gives up electrons.
What is a reducing agent?
300
Better reducing agents are located here on the table.
What is top right?
300
A measure of the driving force produced by a spontaneous redox reaction in a voltaic cell at standard conditions.
What is standard voltage?
300
The randomness of a substance, it increases with disorder.
What is entropy?
400
The oxidation numbers for each element in KCl.
What is +1 for K and -1 for Cl?
400
A particular oxidizing agent will oxidize anything here on the table.
What is above it and to the right?
400
Oxidized and reduced species do not need to be separated by a salt bridge in this type of cell.
What is an electrolytic cell?
400
This states that the entropy of a pure and perfect crystal at absolute zero is zero.
What is the third law of thermodynamics?
500
The oxidation numbers for each element in Cr2O72-.
What is +6 for Cr and -2 for O?
500
A particular reducing agent will reduce anything here on the table.
What is below it and to the left?
500
The charge of the anode in a voltaic cell is this, and in an electrolytic cell is this.
What is negative in voltaic, positive in electrolytic?
500
This is the equation used to relate Gibbs free energy change, change in enthalpy and change in entropy.
