Answer:
equilibrium will shift to the right, and more NH3 will be formed
Step-by-step explanation:
N2(g) + 3H2(g) ---> 2NH3(g)
1 mol +3 mol 2 mol
4 mol 2 mol
When we increase the pressure, the pressure will try to restore old value, so it has to become lower. Pressure is lower when number of particles is less
4 <2, so equilibrium will shift to the right, and more NH3 will be formed.
