When enough NaCl(s) is added to the compartment containing gold to make the [Cl -] , the cell potential is observed to be 0.31 V. Assume that Au3+ is reduced and assume that the reaction in the compartment containing gold is
Au3+(aq) + 4Cl- (aq) ↔ AuCl4- . Calculate the k for this reaction at 250C.

In the reaction you have written, Au^+3 is not reduced. It is +3 on the left and +3 on the right. Cl^- is not reduced or oxidized either.
so how do you solve this problem?
