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.
Ecell = 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 Ecell using the following steps:
Step 1: Identify the anode and the cathode in the reaction
Step 2: Calculate the cell potential of the reaction.
Step 3: Calculate the ratio of products to reactants using the Nernst Equation.
What is the ratio of products to reactants for a dead battery in a NaAl cell?
1) about 1053
3) about 10106
4) about 10-106
