Question

According to LeChâtelier's principle, predict whether adding H20 causes the system to shift in the direction of reactants, products, or no change.
NH4 + (aq) + H20(l) = NH3 (aq) + H30+(aq)
products
reactants
no change

Answer 1

According to Le Châtelier's principle, if we add more H2O to the system, the equilibrium will shift in the direction that opposes the increase in H2O concentration. In this case, adding H2O increases the concentration of the reactant NH4+, so the system will shift in the direction of the products NH3 and H3O+. Therefore, adding H2O will cause the system to shift towards the products.
