In a voltaic cell, there exists a Fe/Fe2+ half-cell and a Sn/Sn2+ half-cell at a temperature of 25°C. The initial concentrations of Sn2+ and Fe2+ are 5.26 mol L-1 and 0.176 mol L-1, respectively. Fe2(aq) + 2e → Fe(s) E° = -0.45 V Sn2(aq) + 2e → Sn(s) E° = -0.14 V What are the concentrations of Sn2+ and Fe 2+ when the cell potential decreases to 0.26 V?

Question
In a voltaic cell, there exists a Fe/Fe2+ half-cell and a Sn/Sn²* half-cell at a temperature of 25°C. The initial concentrations of Sn2+ and Fe2+ are 5.26 mol L-1 and 0.176 mol L-1, respectively. Fe2+(aq) + 2e → Fe(s) E° = -0.45 V Sn2 (aq) + 2e → Sn(s) E° = -0.14 V What are the concentrations of Sn2+ and Fe2+ when the cell potential decreases to 0.26 V?
