Answer the following questions based on the reaction provided. Eu3 (aq) + Au(s) + 4Br (aq) → AuBra (aq) + Eu2*(aq) E°(V) Half Reaction AuBra (aq) + 3e' → Au(s) + 4Br(aq) Eu*(aq) + e → Eu²*(aq) -0.858 -0.43 а. Balance the simple redox reaction. b. Determine the E°cell for the reaction. Determine the Ecell with the following concentrations: [Eu3*] = 0.750 M С. [Br] = 0.444 M [AuBr4] = 0.0250 M [Eu2*] = 0.0330 M d. Did the reaction become better or worse with the new concentrations? Explain your answer.
