What will happen in this reaction: NH3 + H2 = NH4 when x amount of NH4 is added, equilibrium is reached, then 2x is removed.

to the product side because the amount taken out is greater than amount that is added?

if amount added is x and amount removed is also x, then would the reaction be unaffected

In order to determine what will happen in the reaction NH3 + H2 = NH4, we need to consider the stoichiometry of the reaction and understand the concept of equilibrium.

The given reaction is a combination of ammonia (NH3) and hydrogen gas (H2) to form ammonium (NH4) ions. This reaction can be represented by the balanced equation:

NH3 + H2 = NH4

When a certain amount, called 'x,' of NH4 is added to the reaction, it will initially shift the reaction toward the product side in order to establish a new equilibrium. This occurs because the concentration of NH4 increases due to the addition.

However, it's important to note that at equilibrium, the forward and reverse reactions are occurring at the same rate, which means the concentrations of all the species involved remain constant over time. This is typically achieved when the system is closed and there are no external factors affecting the reaction.

Now, let's consider the second part of the question: when 2x amount of NH4 is removed. If the amount removed is equal to the amount added (2x = x), the reaction would still be at equilibrium because the concentrations of all species would remain unchanged. In this case, the reaction would be unaffected since the amounts added and removed are balanced.

However, if the amount removed is greater than the amount added (2x > x), the system would be disturbed. To restore equilibrium, the reaction would shift towards the reactant side in order to replenish the removed NH4. The shift occurs to minimize the change in concentration.

In summary, whether the reaction would be affected or not depends on the ratio between the amounts added and removed. If the amounts are equal, the reaction remains at equilibrium, but if the amount removed is greater, the reaction will shift to restore equilibrium by favoring the reactant side.
