Chapter 15, Problem 17QP

Write the expressions for the equilibrium constants $K_p$ of the following thermal decomposition reactions:

(a)

${\text{2NaHCO}}_{\text{3}}\left(s\right)\rightleftarrows {\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}\left(s\right){\text{ + CO}}_{\text{2}}\left(g\right){\text{ + H}}_{\text{2}}\text{O}\left(g\right)$

(b)

${\text{2CaSO}}_4\left(s\right)\rightleftarrows \text{2CaO}\left(s\right){\text{ + 2SO}}_{\text{2}}\left(g\right){\text{ + O}}_{\text{2}}\left(g\right)$
