In common words, Le Chatelier's Principle tells us that when a system in equilibrium is subjected to a stress, it will shift to undo what we did to it.
So look at the equation.
3 H2(g) + N2(g) <- -> 2NH3(g) + heat
Adding NH3. So the reaction will try to use up NH3 to get rid of what we added. How can it do that? Shift to the left.
When increasing P, the reaction shifts to the side with fewer mols.
See if you can finish.
Given the following reaction:
3 H2(g) + N2(g) <- -> 2NH3(g) + heat
If the following changes were to occur what direction shift will it have (left or right)
And what will be the reason of the shift
Changes/Stress on system:
Adding NH3
Decreasing the pressure
Adding heat
Removing N2
Increasing the pressure

so when you increase p does that mean it shifts to the left
No i think its to the right
That's right. Increasing P shifts to the side with fewer mols OF GAS. There are 4 mols on the left and 2 on the right so increasing P shifts to the right; decreasing P shifts it to the left.
