question 98

Multiple Choice

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 2 5°C.(The equation is balanced.)
$\quad$$\quad$ Pb(s) + Br₂(l) → Pb²⁺(aq) + 2 Br⁻(aq)
Pb²⁺(aq) + 2 e^- → Pb(s) $\quad$$\quad$ E° = -0.13 V
Br₂(l) + 2 e^- → 2 Br^- (aq) $\quad$$\quad$ E° = +1.07 V
