Solution
Solution Steps
Step 1: Identify the reaction and equilibrium constant expression
The given reaction is:
\[
3 \mathrm{H}_{2}(g) + \mathrm{N}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g)
\]
We need to write the expression for the equilibrium constant \( K \).
Step 2: Write the general form of the equilibrium constant expression
For a general reaction of the form:
\[
aA + bB \rightleftharpoons cC + dD
\]
The equilibrium constant \( K \) is given by:
\[
K = \frac{[C]^c [D]^d}{[A]^a [B]^b}
\]
Step 3: Apply the general form to the given reaction
For the given reaction:
\[
3 \mathrm{H}_{2}(g) + \mathrm{N}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g)
\]
The equilibrium constant expression is:
\[
K = \frac{[\mathrm{NH}_3]^2}{[\mathrm{H}_2]^3 [\mathrm{N}_2]}
\]
