[Given : ${E^0}_{Zn/Z{n^{ + 2}}} = 0.76\,V,$
${E^0}_{Cu/C{u^{ + 2}}} = - 0.34\,V,\,\frac{{2.303\,RT}}{F} = 0.06,\log 2 = 0.30]$
Select the incorrect option is
$\frac{2}{3} Al_2O_3 \rightarrow \frac{4}{3} Al + O_2,\,$ $\Delta G = +966\,kJ\,mol$
The potential difference needed for electrolytic reduction of $Al_2O_3$ at $500^o C$ is at least ...... $V$.
$C{O_2} + 2{H_2}O\, \rightleftharpoons {H_3}{O^ + } + HCO_3^ - $
for which the equilibrium constant is $3.8 \times 10^{-7}$ and $pH = 6.0$. The ratio of $[HCO_3^- ]$ to $[CO_2]$ would be :-
$(I)$ Number of $S-S$ bonds in $H_2S_nO_6$ are $(n + 1)$
$(II)$ When $F_2$ reacts with water gives $HF, O_2$ and $O_3$
$(III)$ $LiNO_3$ and $BaCl_2$ compounds are used in fire works
$(IV)$ $Be$ and $Mg$ hydrides are ionic and polymeric
