QUESTION 9

Given the following standard reduction potentials, determine K for the following reaction at 25°C. Report your answer to 3 significant figures in scienitific notation using the format of 6.022E23 for 6.022 × 10²³.

Pb²⁺_(aq) + SO₄²⁻_(aq) → PbSO_{4 (s)}

E°_red

Pb²⁺_(aq) + 2e⁻ → Pb _(s) -0.126 V

PbSO_{4 (s)} + 2e⁻ → Pb_(s) + SO₄²⁻_(aq) -0.356 V

		E°_red
Pb²⁺_(aq) + 2e⁻ → Pb _(s)		-0.126 V
PbSO_{4 (s)} + 2e⁻ → Pb_(s) + SO₄²⁻_(aq)		-0.356 V
