Which olectrode is the cathode? Match the words in the left column to the appropriate blanks in the sentences on the right. Consider the following voltaic cell. \[ \mathrm{Fe}^{2+}(\mathrm{aq})+2 \mathrm{e}^{-} \rightarrow 2 \mathrm{Fe}(\mathrm{s}) \quad E_{\text {ind }}^{4}=-0.44 \mathrm{~V} \] Part B What is the standard emt generated by this cell? Express your answer in volts to two decimal places. A voltaic cell involves a redox reaction, one with \( E_{\text {cell }}^{\circ} \). To achieve the required \( E_{\text {cell }}^{\circ} \), the half-reaction with the more \( E_{\text {red }}^{\circ} \) occurs at the cathode. Therefore, the is the cathode. Consider the folowing voltaic cell. What is the change in the cell voltage when the ion concentrations in the cathode half-call are incroased by a factor at 10 ? Express your answer to three significant figures with the apprepriate units. \( \mathrm{Fe}^{-\pi}(\mathrm{aq}]+2 e^{-} \rightarrow 2 \mathrm{Fe}(8) \quad E_{\mathrm{rid}}^{\mathrm{e}}=-0.44 \mathrm{~V} \quad \) Part D What is the change in the cell voltage when the ice concentrasons in the anode half-cell are increased by a tactor of 107 Express your answer to three significant figures with the appropeiate units.
