$O(g) + e^- \to O^-(g); \Delta H = - 142 \,kJ \,mol^{-1}$
$O^-(g) + e \to O^{2-} (g); \Delta H = 844\, kJ \,mol^{-1}$
This is because
$Zn(s)\,\,|,\,Zn^{+2}_{(aq.)}\,\,|| Ag^+_{(aq.)}\,\,| Ag(s)$
$E^o_{Zn^{+2}/Zn}\,\,=\,-\,0.76V\,\, ;\,\, E^o_{Ag^+ /Ag}\,\, = 0.80V$
$SO_3(g) \rightleftharpoons SO_2(g)+ \frac{1}{2} O_2(g)$
is $K_c= 4.9 \times 10^{-2}.$ The value of $K_c$ for the reaction
$2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$
will be
