Which Statement About a Voltaic Cell Is Not Correct

Multiple Choice

Which statement about a voltaic cell is not correct?

A) The standard reduction potential is a measure of the propensity for a reduction half-reaction to occur when concentrations are 1 M, the pressure is 1 atm, and the temperature is 298 K.
B) A reduction half-reaction with a standard reduction potential, , when reversed becomes an oxidation half-reaction with  .
C) The standard cell potential, , is a measure of the electromotive force (emf) generated by the cell reactions at 298 K when concentrations are 1 M and the pressure is 1 atm.
D) The emf of a cell is a measure of the force with which the cell pumps electrons from the cathode to the anode.
E) The cell voltage measured with a voltmeter is not necessarily the standard cell potential.
