how will the following systems react when an increase in pressure occurs? note all species are gases N2O4<-->2NO2
frez [133]

 N2O4 ↔ 2NO2

The  following system  react as below  when  increase in pressure  occurs

The equilibrium   will  shift towards the left (more N2O4  is produced)

   <em><u>Explanation</u></em>

When  pressure increases  the equilibrium  shift toward  the side  of reaction with fewer  moles of gas.

 In the reaction  of N2O4 ↔  2 NO2  there  is only  1  moles   of N2O4  and 2 moles of NO2.

Therefore increase  in pressure led to shift of equilibrium towards the left. ( more N2O4 is produced)

Sulfur trioxide is a gas that reacts with liquid water to produce aqueous sulfuric Acid or acid rain what is the equation for th
bearhunter [10]

Answer:

SO₃(g) + H₂O(l) → H₂SO₄(aq)

Explanation:

The<em> molecular formula for the involved species</em> are:

  • Sulfur trioxide = SO₃. ("trioxide" indicates the presence of 3 oxygen atoms).
  • Water = H₂O
  • Sulfuric acid = H₂SO₄

With the above information in mind we can proceed to write the reaction equation:

  • SO₃(g) + H₂O(l) → H₂SO₄(aq)
