Question

Select the true statement below.
A. a spontaneous redox reaction equation will have the stronger oxidizer and stronger reducer as products
B. a salt bridge should contain ions that will participate in the redox reaction
C. in a voltaic cell, the difference in chemical potential energy between higher energy reactants and lower energy products is converted into electrical energy
D. in an electrolytic cell, the difference in chemical potential energy between lower energy reactants and higher energy products is converted into electrical energy
E. in a voltaic cell, electrons flow from the cathode to the anode, giving the anode a negative charge

I feel like it might be D but I don't know. Can you explain the other statements why it isn't true?

Answer 1

I don't like any of the answers.
A can't be true. The stronger oxidizing agent and stronger reducing agent are the reactants. Think MnO4^- + Fe^2+ ==> Mn^+ + Fe^3+.

B isn't true. You don't want the salt bridge entreing into the cell reaction.

C. Comes the closest to being true I think. The main problem I have with this is that it isn't ALL converted to energy.

D. An electrolytic cell USES electrical energy; it doesn't produce electricity.

E. In a voltaic cell the anode is negative and the cathode is positive. Electrons from from the anode to the cathode.

Answer 2

Thank you for clearing that up!
