When [Ag+] = 1.15 M, the observed cell potential at 298 K for an electrochemical cell with the reaction shown below is 1.607 V. What is the Cr3+ concentration in this cell? 3A9+(aq) + Cr(s) — 3Ag(s) + Cr3+ (aq) + [Cr3+] = mol/L Submit idation and reduction half-reactions. These The first step is to separate the overall reaction into are shown here. + Agt(aq) + e - Ag(s) reduction Cr(s) —— Cr3+ (aq) + 3e oxidation The next step is to determine Eºcell using standard half-cell potentials. These are tabulated and displayed below. Ag+(aq) + - Ag(s) E° = 0.799 V Cr3+ (aq) + 3e — Cr(s) 0 = -0.740 V What is the standard cell potential? v Submit
