Calculate the value of $E^\circ_{\text{cell}}$, $E_{\text{cell}}$ and $\Delta G$ that can be obtained from the following cell at $298\text{ K}$.
$\text{Al}/\text{Al}^{3+}(0\cdot01\text{M}) \parallel \text{Sn}^{2+}(0\cdot015\text{M})/\text{Sn}$
Given $E^\circ_{\text{Al}^{3+}/\text{Al}} = -1\cdot66\text{ V}$; $E^\circ_{\text{Sn}^{2+}/\text{Sn}} = -0\cdot14\text{ V}$
Answer
Answer
Official answer keyFormula used: Standard emf of a cell: E0cell = E0cathode - E0anode with E0anode = -1.66 V, E0cathode = -0.14 V, so E0cell = 1.52 V
$E^\circ_{cell} = 1.52\ \mathrm{V}$, $E_{cell} = 1.5056\ \mathrm{V}$, $\Delta G = -871742\ \mathrm{Joules}$
Final answer: -871742 J
