The equilibrium constant for the reaction of fluorine and oxygen to form oxygen difluoride (OF2) is 40.1 at 298 K:

$$F2(g) + ½ O 2(g) ↔2 OF2(g)$$

Suppose some OF2 is introduced into an evacuated container at 298 K and allowed to dissociate until its partial pressure reaches an equilibrium value of 1.00 atm. Calculate the equilibrium partial pressures of F2 and O2 in the container .

Calculate the pH of the solution.

[OH$^-$] = 4.3 X 10$^{-5}$M

Phenol, once known as carbolic acid, $\mathrm{HC}_6 \mathrm{H}_5 \mathrm{O}$, is a weak acid. It was one of the first antiseptics used by Lister. Its $K_{\mathrm{a}}$ is $1.1 \times 10^{-10}$. A solution of phenol is prepared by dissolving $14.5 \mathrm{~g}$ of phenol in enough water to make $892 \mathrm{~mL}$ of solution. For this solution, calculate (a) $\mathrm{pH}$ (b) % ionization
