Chapter 16, Problem 32E

Calculate K_pfor each reaction.

a. ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\left(g\right)\rightleftharpoons 2{\text{NO}}_{\text{2}}\left(g\right)$ $K_c=5.9\rightleftharpoons \text{1}{0}^{-3}$ (at 298 K)
b. ${\text{N}}_{\text{2}}\left(g\right)+3{\text{H}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons 2{\text{NH}}_3\left(g\right)$ $K_c=3.7\times \text{1}{0}^8$ (at 298 K)
c. ${\text{N}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons 2\text{NO}\left(g\right)$ $K_c=4.10\times \text{1}{0}^{-31}$ (at 298 K)
