16.4 Exercise 12

Calculate the equilibrium constant at 25 °C for each of the following reactions from the value of ΔG° given.

(a) $\text{O}_{2} \left(g\right) + \text{2F}_{2} \left(g\right) \rightarrow \text{2OF}_{2} \left(g\right) \Delta G ° = −\text{9}.\text{2 kJ}$

(b) $\text{I}_{2} \left(s\right) + \text{Br}_{2} \left(l\right) \rightarrow \text{2IBr} \left(g\right) \Delta G ° = \text{7}.\text{3 kJ}$

(c) $\text{2LiOH} \left(s\right) + \text{CO}_{2} \left(g\right) \rightarrow \text{Li}_{2} \text{CO}_{3} \left(s\right) + \text{H}_{2} \text{O} \left(g\right) \Delta G ° = −\text{79 kJ}$

(d) $\text{N}_{2} \text{O}_{3} \left(g\right) \rightarrow \text{NO} \left(g\right) + \text{NO}_{2} \left(g\right) \Delta G ° = −\text{1}.\text{6 kJ}$

(e) $\text{SnCl}_{4} \left(l\right) \rightarrow \text{SnCl}_{4} \left(l\right) \Delta G ° = \text{8}.\text{0 kJ}$
