1.	Which of the following statements is incrrect ?A. `E _("electrode" )^(Ө)` changes sign whenever we reverse a cell reaction.B. The half-cell reactions are not reversible.C. Changing the stoichoimetric coefficients of a half-cell reaction does not affect the value of `E^(Ө)`D. The more positive the `E^(Ө)` value, the greater the tendency for the substance to be reduced.
Answer» Correct Answer - B The half-cell reactions are reversible. Depending upon the conditions, any electrode can act either as an anode or as a cathode.
