6. A. Calculate the potential of the cell where the reaction: $2 \mathrm{HClO}_{2} 3 / 4 ® \mathrm{HClO}^{3}+\mathrm{ClO}_{3}-+\mathrm{H}^{+}$ occurs if: $\left[\mathrm{HClO}_{2}\right]=0.01 \mathrm{M} ;[\mathrm{HClO}]=0.10 \mathrm{M} ;\left[\mathrm{ClO}_{3}-\right]=0.10 \mathrm{M}$ and $\mathrm{pH}=5.0$
B. Taking all species to be $1 \mathrm{M}$ except $\mathrm{HClO}_{2}$, calculate the concentration of $\mathrm{HClO}_{2}$ at which the reaction would no longer be spontaneous.

∻Solution∻ ‖ 1 ⋮ **Write the balanced half-reactions and the overall reaction**: The given reaction is not balanced. We need to balance it in terms of atoms and charges to use it in further calculations. ‖ ‖ 2 ⋮ **Calculate the standard cell potential (E°)**: The standard cell potential is calculated using the standard reduction potentials of the half-reactions. However, since the standard reduction potentials are not provided, we will assume that the Nernst equation will be used to calculate the cell potential under non-standard conditions. ‖ ‖ 3 ⋮ **Use the Nernst equation**: The Nernst equation relates the cell potential to the standard cell potential and the reaction quotient (Q). The equation is $E = E° - \frac{0.0592}{n} \log Q$, where $n$ is the number of moles of electrons transferred in the balanced equation, and $Q$ is the reaction quotient. ‖ ‖ 4 ⋮ **Calculate the reaction quotient (Q)**: For the reaction $2 \mathrm{HClO}_{2} \rightarrow \mathrm{HClO} + \mathrm{ClO}_{3}^{-} + \mathrm{H}^{+}$, the reaction quotient $Q$ is given by $Q = \frac{[\mathrm{HClO}][\mathrm{ClO}_{3}^{-}][\mathrm{H}^{+}]}{[\mathrm{HClO}_{2}]^2}$. We can calculate $Q$ using the given concentrations and the pH of the solution. ‖ ‖ 5 ⋮ **Calculate the pH and the concentration of $\mathrm{H}^{+}$**: The pH is given as 5.0, which means the concentration of $\mathrm{H}^{+}$ is $10^{-5} \mathrm{M}$. ‖ ‖ 6 ⋮ **Plug the values into the Nernst equation**: Substitute the calculated values of $Q$ and the concentration of $\mathrm{H}^{+}$ into the Nernst equation to find the cell potential $E$. ‖ ‖ 7 ⋮ **Determine the spontaneity condition**: For a reaction to be spontaneous, the cell potential $E$ must be positive. To find the concentration of $\mathrm{HClO}_{2}$ at which the reaction is no longer spontaneous, we set $E$ to zero and solve for $[\mathrm{HClO}_{2}]$. ‖ ∻A Answer∻ ⚹ [Insert final answer for part A here] ⚹ ∻B Answer∻ ⚹ [Insert final answer for part B here] ⚹ ∻Key Concept∻ ⚹ The Nernst equation is used to calculate the cell potential under non-standard conditions and determine the spontaneity of a reaction. ⚹ ∻Explanation∻ ⚹ The Nernst equation allows us to relate the cell potential to the concentrations of the reactants and products.
