The reaction N2O4(g)=2NO2(g)is at equilibium.Increasing the pressure will have what effect on the equilibrium?

Question

1. The equilibrium is shifted to the right
2. The equilibrium remains unchanged.
3. The equilibrium is shifted to the left

Answer 1

the equilibrium is shifted to the left. since there are more moles of gas on the products side of the reaction, according to le chatelier's principle it will try to "undo" this pressure, and this will happen by going to a state with less mole of gas, which will cause the reaction to shift to the left.

Answer 2

Why don't you do your homework yourself?

Anyway, here is a clue. Find the number of moles of gas on each side. Increasing the pressure will shift the equilibrium to the side with less moles.

Answer 3

3.

Turning two molecules of NO2 into one of N2O4 decreases the pressure, thus relieving the stress on the equilibrium.
