A galvanic cell at a temperature of 25.0 °C is powered by the following redox reaction: 2Cr3+ (aq) + 3 Ca(s) → 2Cr(s) + 3Ca²+ (aq) Suppose the cell is prepared with 6.35 M Cr³+ in one half-cell and 0.492 M Ca2+ in the other half. Calculate the cell voltage under these conditions. Cr3+ (aq) + 3e → Cr(s) Ered = -0.744 V Ca2+ (aq) + 2e → Ca(s) Ered = -2.868 V The standard cell potential (E°) for this galvanic cell is [Select] V. There are [ Select] + moles of electrons transferred during to operate this galvanic cell. Under these conditions, the reaction quotient is [Select] and the cell volatage is [Select] V. In order to increase the cell voltage for this cell, [Select ]
