Is Cr^3+(aq) anrd Pb(s) a spontaneous redox reaction in a voltaic cell

1 answer

The spontaneity of a redox reaction can be determined using the standard reduction potentials of the half-reactions involved. Unfortunately, the standard reduction potential for Cr^3+(aq) to Cr(s) and Pb^2+(aq) to Pb(s) are not provided. Without this information, it is not possible to determine the spontaneity of the reaction and whether it would occur in a voltaic cell.
