At $1127 \mathrm{K}$ and $1$atm pressure, a gaseous mixture of $\mathrm{CO}$ and ${\mathrm{CO}}_2$ in equilibrium with solid carbon has $90.55\%$ $\mathrm{CO}$ by mass

$\mathrm{C}\left(\mathrm{s}\right) + {\mathrm{CO}}_2\left(\mathrm{g}\right) \to 2\mathrm{CO}\left(\mathrm{g}\right)$

Calculate ${\mathrm{K}}_{\mathrm{c}}$ for this reaction at the above temperature. 

Find out the ${\mathrm{p}}^{\mathrm{H}}$ of the following solution:

$0.3 \mathrm{g}$ of $\mathrm{Ca}(\mathrm{OH}{)}_2$ dissolved in water to given $500 \mathrm{mL}$ of the solution.

The ${\mathrm{p}}^{\mathrm{H}}$ of $0.005 \mathrm{M}$ codeine${\mathrm{C}}_{18}{\mathrm{H}}_{21}{\mathrm{NO}}_3$ solution is $9.95$. Calculate its ionization constant and ${\mathrm{p}}^{\mathrm{Kb}}$.

Calculate the degree of ionization of $0.05 \mathrm{M}$ acetic acid if its ${\mathrm{pK}}_{\mathrm{a}}$ value is $4.74$. How is the degree of dissociation affected when its solution also contains $0.01 \mathrm{M}$ in $\mathrm{HCl}$?
