Chapter 18, Problem 97RQ

Equilibrium Constants and $\Delta G°$

Calculate the value of the thermodynamic equilibrium constant for the following reactions at $\text{25 °C}$. (Refer to the data in Appendix C.)

(a) ${\text{2PCl}}_{\text{3}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\rightleftharpoons 2{\text{POCl}}_{\text{3}}\left(g\right)$

(b) ${\text{2SO}}_{\text{3}}\left(g\right)\rightleftharpoons 2{\text{SO}}_2\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)$
