Answer:
if gibbs free energy change is negative then the reaction is spontaneous
Since rain is water getting evaporated and condensed, it's equivalent to being distilled. Distilled water is pure water, so I'd guess the normal pH of rain is 7 - which is neutral (neither acidic nor alkaline)
However, when Sulfur Oxides and Nitrogen Oxides mix into the clouds, acid rain could be produced. This isn't "normal rain", though
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.
