A galvanic cell is set up from electrodes A and B Electrode \A: {\Cr}_{2} {\O}_{7}^{2-} \/ {\Cr}^{3+}, \E^\circ_{{\red}}=+1.33 {\V} Electrode \B: {\Fe}^{3+} \/ {\Fe}^{2+}, \E^\circ_{{\red }} =0.77 V Which of the following statements is false ?

Correct Answer is : None of these

Standard e.m.f of the cell is 0.56 {\V}

Current will flow from electrode A to B in the external circuit

A will act as cathode and have positive polarity
