Answer:
4. The equilibrium will shift to favor formation of NO2(g)
Explanation:
According to La Chatalier's Principle which states that when an equilibrium system undergoes changes either in temperature, volume or concentration; there will be in a change in the system in order to reach equilibrium.
From the above equation,
N2O4(g) ⇀↽ 2 NO2(g)
From the above reaction, there are 2 moles of gaseous product on the left and 1 mole of gaseous reactant.
Therefore, there are more moles of gases in the left hand side than the right hand side.
Because a decrease in volume favors the direction that produces fewer moles, an increase in volume will therefore shift this system towards the side with more moles of gases that is, more products are formed hence, this system will shift to right and produce more moles of products i.e more NO2(g) formed.
On an approximate scale, A child breaths 20 times a minute as compared to only 12 to 16 in resting phase of an Adult.
So, In 60 minutes (1 hour), They breathe = 20 * 60 = 1200
In 24 hours (1 day), They breathe = 1200 * 24 = 28,800
In short, Your Answer would be: 28,800
Hope this helps!
