2. - is a most widely used process to produce ammonia.
- It is mainly the reaction of nitrogen from the air with
hydrogen from natural gas to produce ammonia.

3. Chemical reaction
Chemical reaction is the process that leads transformation of one
set of chemical substances in two another substances. In most
chemical reactions a set of substances completely transfer into
another substances.
Example - A + B C
Here there is no left over A or B. Nearly all of the atoms are converted
into C.

9. Reversible Chemical reaction
In Reversible Chemical reaction the chemical reaction doesn’t go
to completion. Instead it involves both forward reaction ( to
produce product) and back reaction ( to produce reactants ).
Example - A + B C
Here A and B react to produce C.

17. Definition
The state of a reaction in which both the concentration of the reactant and
the product stays the same through out the reaction is called Equilibrium
state.

Nitrogen Hydrogen Ammonia
When both the forward and the reverse reactions start going at the same rate ,
the reaction achieve equilibrium state.
For a reaction to enter equilibrium state it needs to take place in a closed
system.

36. When pressure increases , the system will shift so the least
number of gas molecules are formed. The more gas molecules
there are, the more collisions there are. These collisions and
the presence of gas molecules are what cause the pressure to
increase. Also, when pressure decrease, the system will shift so
the highest number of gas molecules are produced.
