The balanced chemical equation for the reversed reaction is;
- 2NO2(g) ==> N2(g) + 2O2(g).
<h3>Reverse Reaction</h3>
The given chemical equation in equilibrium is;
- N2(g) + 2O2(g) ↽−−⇀2NO2(g).
Hence, it follows that; the reversed reaction with indication of phase changes is as follows;
- 2NO2(g) ==> N2(g) + 2O2(g).

Based on the calculations, the pressure of this gas sample at 27°C is equal to 0.17 atm.
<h3>How to determine the final pressure.</h3>
In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;
<u>Where:</u>
- k is the constant of proportionality.
Substituting the given parameters into the formula, we have;
Final pressure = 0.17 atm.

In the past two decades, the number of teenage pregnancies has dropped dramatically across all ethnic groups.
<h3>Why has
teenage pregnancies has dropped dramatically across all ethnic groups?</h3>
The teenage pregnancies has dropped dramatically across all ethnic groups because of the education , there are alot of parents that are now educated to educate their children about danger of teenage pregnancies.
Also, there has been increased in protective measure by the government to reduce teenage pregnancies, hence, In the past two decades, the number of teenage pregnancies has dropped dramatically across all ethnic groups.
