$2KCl{O_4}(s) \rightleftharpoons 2KCl(s) + 3{O_2}(g)$
If $\Delta {H^o} = 25\,kcal/mol$ and $\Delta {S^o} = 50\,cal/K$, at what temperature equilibrium will be established in the container. (Ignore variation of $\Delta {H^o}$ and $\Delta {S^o}$ with temperature.)......$K$
$C{r_2}O_7^{2 - } + F{e^{2 + }} + {C_2}O_4^{2 - } \to C{r^{3 + }} + F{e^{3 + }} + C{O_2}$ (Unbalanced)
