Question
The value of KP for the equilibrium NH4HS(s) $\rightleftharpoons$NH3(g) + H2S(g) at a certain temperature and total 2 atm pressure at equilibrium will be
Options
A.0.25 atm2
B.1.0 atm2
C.4.0 atm2
D.1.0 atm
Solution
$K = \frac{\left\lbrack H_{2} \right\rbrack^{4}}{\left\lbrack H_{2}O \right\rbrack^{4}} = \left( \frac{\frac{1.2}{2}}{\frac{54}{18}} \right)^{4} = 0.0016$
