N2(g) + 3H2(g) + 2NH3 (9)
What will happen if pressure is increased?

equilibrium will shift to the right, and more NH3 will be formed

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.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
