Answer:
C) Toward the reactants.
Explanation:
Based in the reaction:
3H₂(g) + N₂(g) → 2NH₃(g)
Equilibrium constant, K, is:
K = 4.51x10⁻⁵ = [NH₃]² / [H₂]³[N₂]
<em>Where gas concentrations are equilibrium concentrations.</em>
Reaction quotient, Q, is:
Q = [NH₃]² / [H₂]³[N₂]
<em>But concentrations not necessary are in equilibrium</em>
If Q = Ksp, the reaction is in equilibrium, if Q > Ksp, the reaction goes toward reactants and if Q < Ksp, the reaction goes toward products.
Replacing with values of the problem:
Q = [5.4]² / [1.4]³[2.7] = 3.936
As Q > Ksp, <em>the reaction goes toward reactants</em>.
Right answer is:
<em>C) Toward the reactants.</em>
