We are asked to calculate for the **ratio of products to reactants for a dead battery in a NaAl cell**.

Recall that the** Nernst Equation** relates the concentrations of compounds and cell potential.

$\overline{){{\mathbf{E}}}_{{\mathbf{cell}}}{\mathbf{=}}{\mathbf{E}}{{\mathbf{\xb0}}}_{{\mathbf{cell}}}{\mathbf{-}}\mathbf{\left(}\frac{\mathbf{0}\mathbf{.}\mathbf{05916}\mathbf{}\mathbf{V}}{\mathbf{n}}\mathbf{\right)}{\mathbf{}}{\mathbf{log}}{\mathbf{}}{\mathbf{Q}}}$

E_{cell} = cell potential under non-standard conditions

E°_{cell} = standard cell potential

n = mole e^{-} transferred

Q = reaction quotient = products/reactants

We're going to calculate for the E_{cell} using the following steps:

*Step 1:** **Identify the anode and the cathode in the reaction*** Step 2: **Calculate the cell potential of the reaction.

What is the ratio of products to reactants for a dead battery in a NaAl cell?

1) about 10^{53}

2) 53

3) about 10^{106}

4) about 10^{-106}
