Chapter 13, Problem 25E

Convert the values of K_C to values of K_P to the values of K_P to values of K_c.

(a) ${\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)\rightleftharpoons 2{\text{NH}}_3\left(g\right)$	$K_c=0.50$ at 400 °C
(b) ${\text{H}}_2\left(g\right)+{\text{I}}_2\left(g\right)\rightleftharpoons 2\text{HI}\left(g\right)$	$K_c=50.2$ at 448 °C
(c) ${\text{Na}}_2{\text{SO}}_4\cdot 10{\text{H}}_2\text{O}\left(s\right)\rightleftharpoons {\text{Na}}_2{\text{SO}}_4\left(s\right)+10{\text{H}}_2\text{O}\left(g\right)$	$K_p=4.08\times {10}^{-25}$ at 25°C
(d) ${\text{H}}_2\text{O}\left(l\right)\rightleftharpoons {\text{H}}_2\text{O}\left(g\right)$	$K_p=0.122$ at 50 °C
