Question

Ammonia and oxygen react to form nitrogen and water, like this: Suppose a mixture of NH3, O2, N2, H2O and has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left.

Answer 1

When a mixture of NH3, O2, N2, and H2O reaches equilibrium, the perturbations in the table will cause a change in the composition of the mixture. The direction of the shift can be predicted using Le Chatelier's principle.

When a mixture of NH3, O2, N2, and H2O comes to equilibrium in a closed reaction vessel, the perturbations in the table will cause a change in the composition of the mixture. To predict the direction of the shift, we need to consider Le Chatelier's principle. If the concentration of NH3 is increased, the equilibrium will shift to the left (reverse reaction) to decrease the NH3 concentration. If the concentration of O2 is increased, it will have no effect on the equilibrium since it is not involved in the reaction. If the concentration of N2 or H2O is increased, the equilibrium will shift to the right (forward reaction) to counteract the increase and restore equilibrium.

the perturbations in the table will cause a change in the composition of the mixture. The direction of the shift can be predicted using Le Chatelier's principle.
