Questions & Step-by-Step Solutions
For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what will happen 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 called equilibrium, where the amounts of reactants and products remain constant.
Step 3: Know that Le Chatelier's Principle states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Identify the change: we are decreasing the concentration of NH3 (ammonia).
Step 5: Apply Le Chatelier's Principle: since we decreased NH3, the system will try to increase NH3 back to its original level.
Step 6: Determine the direction of the shift: to produce more NH3, the reaction will shift to the right, which means more N2 and H2 will react to form NH3.
Le Chatelier's Principle – This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
