Exercise \(\PageIndex{1}\)
\[3 H_{2 (g)} + N_{2 (g)} \longleftrightarrow 2 NH_{3 (g)}\]
What is the equilibrium constant expression of the reaction above?
- Answer
-
\(K_{eq} = \dfrac{[NH_{3}]^{2}}{[H_{2}]^{3}[N_{2}]}\)
Exercise \(\PageIndex{1}\)
\[2 SO_{2 (g)} + O_{2 (g)} \longleftrightarrow 2 SO_{3 (g)}\]
The Keq of the reaction above is 3.4 x 102. Is the equilibrium mixture mostly SO2 and O2 or mostly SO3?
- Answer
-
mostly SO3
Exercise \(\PageIndex{1}\)
\[C_{(s)} + 2 S_{(g)} \longleftrightarrow CS_{2 (g)}\]
What is the equilibrium constant expression of the reaction above?
- Answer
-
\(K_{eq} = \dfrac{[CS_{2}]}{[S]^{2}}\)
Exercise \(\PageIndex{1}\)
\[Pb^{2+}_{(aq)} + 2 Cl^{1–}_{(aq)} \longleftrightarrow PbCl_{2 (s)}\]
What is the equilibrium constant expression of the reaction above?
- Answer
-
\(K_{eq} = \dfrac{1}{[Pb^{2+}][Cl^{1–}]^{2}}\)
