Questions & Step-by-Step Solutions
For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what happens if the concentration of NH3 is decreased?
Step 1: Understand the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g) means nitrogen and hydrogen gases react to form ammonia.
Step 2: Recognize that this reaction can reach a state of balance called equilibrium, where the rates of the forward and reverse reactions are equal.
Step 3: Identify what happens when the concentration of NH3 (ammonia) is decreased: there is less NH3 present in the system.
Step 4: Apply Le Chatelier's Principle, which states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 5: Since NH3 is decreased, the system will try to produce more NH3 to restore balance.
Step 6: This means the equilibrium will shift to the right, favoring the production of more NH3 from N2 and H2.
Le Chatelier's Principle – When a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance.
