by increasing pressure and decreasing temperature
Heat
Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions,
the position of equilibrium shifts to counteract the change.
Let's analyze each option:
Option 1: Increasing the concentration of
NH3(g) • Adding more
will shift the equilibrium to the left, favoring the formation of
and
• This does not shift the equilibrium in the forward direction.
Option 2: Decreasing the pressure
• Decreasing the pressure will favor the side with more moles of gas.
• The left side has 4 moles (1
and 3
while the right side has 2 moles of
• Therefore, decreasing pressure shifts the equilibrium to the left.
Option 3: Decreasing the concentrations of
and
• Reducing the reactants will shift the equilibrium to the left to produce more
and
• This does not favor the forward reaction.
Option 4: Increasing pressure and decreasing temperature
• Increasing pressure favors the side with fewer moles of gas, which is the right side (2 moles of
• Decreasing temperature favors the exothermic reaction, which is the forward reaction in this case.
• Both changes shift the equilibrium in the forward direction.
Therefore, the correct option is 4: Increasing pressure and decreasing temperature.
