Consider the reaction: HF(aq) $\rightleftharpoons$ H$^+$(aq) + F$^-$(aq) For which K$_a$ = 7.2 $\times$ 10$^{-4}$ at 25 $^\circ$C. Calculate $\Delta G$ (J/mol) for the reaction when [HF] = 0.80 M and [H$^+$] = [F$^-$] = 3.7 $\times$ 10$^{-4}$ M at 25 $^\circ$C. Question 17 Calculate the osmotic pressure of a 0.0500 M MgSO$_4$ solution at 25 $^\circ$C. 5 pts Question 18 10 pts A 25.0 mL volume of a sodium hydroxide (NaOH) solution requires 19.6 mL of a 0.189 M hydrochloric acid (HCl) solution for neutralization. A 10.0 mL volume of a nitrous acid (HNO$_2$) solution requires 34.9 mL of the sodium hydroxide solution for complete neutralization. Calculate the concentration of the nitrous acid solution? Question 19 10 pts Consider the equilibrium 2NOBr (g) $\rightleftharpoons$ 2NO (g) + Br$_2$ (g) If 0.166 atm of nitrosyl bromide, NOBr, is allowed to dissociate at 25 $^\circ$C and the partial pressure of Br$_2$ is 0.028 atm at equilibrium, calculate K$_p$ for the dissociation at this temperature.
