Analyse data, including displacement reactions of metals, combustion, corrosion and electrochemical processes to determine redox reactions. Electrochemical cells

Analyse the experimental data to determine which half-reaction occurred at the anode in the electrochemical cell.

Analyse the data in the table to explain whether the reaction between zinc metal and acidified permanganate solution is spontaneous under standard conditions.

Analyse the voltaic cell data to determine which metal is being oxidised at the anode. Cell notation: \( \text{Zn(s)} \mid \text{Zn}^{2+}\text{(aq)} \parallel \text{Ag}^{+}\text{(aq)} \mid \text{Ag(s)} \) Standard reduction potentials: \( \text{Zn}^{2+}\text{(aq)} + 2e^{-} \rightarrow \text{Zn(s)} \quad E^{\circ} = -0.76 \, \text{V} \) \( \text{Ag}^{+}\text{(aq)} + e^{-} \rightarrow \text{Ag(s)} \quad E^{\circ} = +0.80 \, \text{V} \)
