12. The reaction 2NO, (g) = N20,(g) reaches equilibrium. How does increasing the pressure on this system affect the amount o
The amount of N20 remains the same.
The amount of N20 increases.
The amount of N20 decreases.

The amount of N2O4 increases.

Explanation:

Based on LeCh's principle, a change in the state of an equilibrium produce an effect in the system that try to restore the initial equilibrium.

For example, in the problem, the change is the increasing in the pressure. The system will try to decrease the pressure of the system. To decrease the pressure the system needs to decrease the moles of gas. As 2 moles of NO2 produce 1 mole of N2O4, the system will:

Shift to the right increasing the amount of N2O4 and decreasing the amount of NO2. Right option is:
