The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Answer:
If NH4+ is removed, the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
Explanation:
A solution of ammonia NH3(aq) can be written through the following equation:
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) + OH⁻(aq)
If the concentration of one of the reactants changes, the balance will shift in such a way that the change in concentration is counteracted.
If NH4+ is removed, now there is less product, so the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
This principle is due to the fact that the equilibrium constant for this reaction is constant at a certain temperature. The ratio of reactants and products is fixed. Any change in concentration disrupts the balance and will result in the balance being restored.
