229- Considering the data in the figure below, which shows the amount of reactants and products at equilibrium at a certain temperature in a closed vessel of one liter, and if we can keep the volume of the vessel constant at a fixed temperature, what will happen to the equilibrium upon decreasing? (All substances are gaseous.)
[Figure: A container showing reactants and products with: $0.8\ \mathrm{mol}\ A_2$ $0.8\ \mathrm{mol}\ X_2$ $0.04\ \mathrm{mol}\ AX$ on the reactants side and products side]
  1. [$\mathbf{(1)}$] $2.5\times10^{-3}$, equilibrium is maintained.
  2. [$\mathbf{(2)}$] $1.66\times10^{-3}$, equilibrium is maintained.
  3. [$\mathbf{(3)}$] $2.5\times10^{-3}$, equilibrium shifts in the forward direction.
  4. [$\mathbf{(4)}$] $1.66\times10^{-3}$, equilibrium shifts in the reverse direction.
