- 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.

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.

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. and C decompose to produce

Reversible Chemical reaction

Reverse reaction is possible.

During Haber process Nitrogen and Hydrogen react and form ammonia. This reaction is reversible that it involves both the production

of reactant and product.

N2 + 3H2 2NH3

In the forward reaction , with the help of a catalyst Nitrogen and hydrogen produce ammonia and the reverse reaction decomposes ammonia in to

Nitrogen and Hydrogen.

Application in Haber Process

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.

FeOH

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.

FeOH

Once an equilibrium is established , the concentration of the reactant and the product stays the same through out time ...

But what will happen if the concentration of one of the substances change ... ?

Decrease in Ammonia Concentration


Effect of

The reaction move to the right and more ammonia will be produced.


If a system at equilibrium experiences a change, the system will shift its equilibrium to try to compensate for the change. In doing this new equilibrium will be

achieved.

When the temperature of the reaction decrease , the exothermic reaction will be favoured because it will

produce the heat that was lost.

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.
