Question

Assume that you want to construct a voltaic cell that uses the following half-reactions shown below: (a) Construct a voltaic cell that includes the salt bridge with Na+ and NO3 ions. (b) What electrode must be in the cathode to generate a standard emf? (c) Label the negative electrode and positive electrode of the cell. (d) Label the direction of electron flow, and label one electrode as the cathode and the other electrode as the anode. (e) Which direction do electrons move through the external circuit? *
A²+ (aq) + 2e- → A (s)
B²+ (aq) + 2 e- → B(s)
Eºred=-0.10 V
Eºred=-1.10 V​

Answer 1

Explanation:

kinetic energy is minimum, potential energy is maximum.

In SHM, kinetic energy is maximum at mean position and zero at the extreme positions while potential energy is zero at mean position and maximum at the extreme positions.
