Three metals, \(A, B \)and \(C\), with solutions of their respective cations are tested in a voltaic cell with the following results:
\(A\) and \(B\): \(A\) is the cathode
\(B\) and \(C\): \(C\) is the cathode
\(A\) and \(C\): \(A\) is the anode
What is the order of the reduction potentials from highest to lowest for the cations of these metals?
