Chapter 15, Problem 21E

Write an expression for the equilibrium constant of each chemical equation:

a. ${\text{SbCl}}_{\text{5}}\left(\text{g}\right)\rightleftharpoons {\text{SbCl}}_{\text{5}}+{\text{Cl}}_{\text{2}}\left(\text{g}\right)$
b. $\text{2BrNO}\left(\text{g}\right)\rightleftharpoons \text{2NO}\left(\text{g}\right)+{\text{Br}}_{\text{2}}$
c. ${\text{CH}}_{\text{4}}\left(\text{g}\right)+{\text{2H}}_{\text{2}}\text{S}\left(\text{g}\right)\rightleftharpoons {\text{CS}}_{\text{2}}\left(\text{g}\right)+{\text{4H}}_{\text{2}}\left(\text{g}\right)$
d. $\text{2CO}\left(\text{g}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{2CO}}_{\text{2}}\left(\text{g}\right)$
