16.3 Exercise 6

Using the relevant $S °$ values listed in Appendix G, calculate $\left(\Delta S °\right)_{298}$ for the following changes:

(a) $\text{N}_{2} \left(g\right) + 3 \text{H}_{2} \left(g\right) \rightarrow 2 \text{NH}_{3} \left(g\right)$

(b) $\text{N}_{2} \left(g\right) + \frac{5}{2} \text{O}_{2} \left(g\right) \rightarrow \text{N}_{2} \text{O}_{5} \left(g\right)$
