Chapter 15, Problem 22E

Find and fix each mistake in the equilibrium constant expressions:

a. ${\text{2H}}_{\text{2}}\text{S}\left(\text{g}\right)\rightleftharpoons {\text{2H}}_{\text{2}}\left(\text{g}\right)+{\text{S}}_{\text{2}}\left(\text{g}\right)$ $\text{Kc}=\frac{\left[{\text{H}}_{\text{2}}\right]\left[{\text{S}}_{\text{2}}\right]}{\left[{\text{H}}_{\text{2}}\text{S}\right]}$
b. $\text{CO}\left(\text{g}\right)+{\text{Cl}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{COCl}}_{\text{2}}\left(\text{g}\right)$ $\text{Kc}=\frac{\left[\text{CO}\right]\left[{\text{Cl}}_{\text{2}}\right]}{\left[{\text{COCl}}_{\text{2}}\right]}$
