Question

I have a question about this one
2N2O(g) ⇋ O2(g) + 2N2(g), what happens to the equilibrium position if the pressure decreases?

Is going to shift to the right or to the left???

Answer 1

Here is a statement to remember. If the pressure of a system in equilibrium
INCREASES the system will shift to the side with the fewer moles of gas (in order to occupy the smaller volume of course). I see 3 mols of gas on the right and 2 on the left..

Answer 2

Then if it Decrease the system will shift to the side with more moles of gas?

Answer 3

yes

Answer 4

it is going to the left side.
