A hypothetical galvanic cell is ${ }^{\ominus} \mathrm{A}_{(\mathrm{s})} \mid \stackrel{+}{\mathrm{A}}(1 \mathrm{M})\|\stackrel{+2}{\mathrm{~B}}(1 \mathrm{M})\| \stackrel{\oplus}{\mathrm{B}}_{(\mathrm{s})}$ and emf of cell is positive. What is the possible cell reaction?

$\quad \mathrm{A}_{(\mathrm{s})}+\stackrel{+B}{B}_{(\mathrm{aq})} \longrightarrow \stackrel{+1}{A}_{(\mathrm{aq})}+\mathrm{B}_{(\mathrm{s})}$

$\quad 2 \mathrm{~A}_{(\mathrm{s})}+\stackrel{+}{\mathrm{B}}_{(\mathrm{aq})} \longrightarrow 2 \stackrel{+1}{\mathrm{~A}}_{(\mathrm{aq})}^{+}+\mathrm{B}_{(\mathrm{s})}$

$\quad \mathrm{A}_{(\mathrm{s})}+2 \stackrel{+2 B}{(\mathrm{aq})}^{+2} \xrightarrow{+1} \mathrm{~A}_{(\mathrm{aq})}+2 \mathrm{~B}_{(\mathrm{s})}$

$\quad 2 \stackrel{+}{\mathrm{A}}_{(\mathrm{aq})}+\mathrm{B}_{(\mathrm{s})} \longrightarrow 2 \mathrm{~A}_{(\mathrm{s})}+\stackrel{+2}{\mathrm{~B}}_{(\mathrm{aq})}$
