Calculate the standard cell potential for the reaction 2 MnO₄^-(aq) + 5 Sn²⁺ (aq) + 16 H⁺ (aq) → 2 Mn²⁺ (aq) + 5 Sn⁴⁺ (aq) + 8 H₂O At a temperature of 298 K.

Quizplus · Accepted Answer

The standard cell potential is calculated using the standard reduction potentials of the half-reactions. The reduction potential for MnO₄⁻ to Mn²⁺ is +1.51 V, and for Sn⁴⁺ to Sn²⁺ is +0.15 V. The cell potential is the difference: 1.51 V - 0.15 V = +1.36 V, which rounds to +1.37 V.
