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.

you didnt put any of the following

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
