Question

Give an example of the reaction where the following is observed.
High pressure is required

Answer 1

There are different reaction conditions to proceed a chemical reaction. Many reactions are there in which high pressure, high temperature conditions, use of a catalyst is required because these conditions will hinder the chemical reaction. Reaction taking place at equilibrium signifies that it is reversible; it can change from reactants to products or vice versa.

Complete answer:
Many reactions are there in which high pressure is required we will study about the most commonly derived reaction in which high pressure is used i.e. Haber’s Process which is the process for the production of ammonia gas. But before starting we must know why high pressure is required? Or how does it affect the reaction?
So when you increase the pressure in any chemical reaction it will suddenly decrease the space in which molecules are moving. Greater the density, higher the number of collisions in the molecules. That's how the reaction looks on increasing the pressure. Let’s study about Haber’s process now:
Haber’s process can be represented as:
${N_2} + 3{H_2}\overset {200atm} \leftrightarrows 2N{H_3}$
This process is generally the production of ammonia gas from nitrogen and hydrogen gas keeping the pressure condition $200atm$ or above also.

Note:
We have to know that the reaction is taking place in equilibrium that means rate of forward reaction is equals to rate of backward reaction. This is a complete balanced chemical equation as the number of moles for each reactant is the same as that of the product. It is an industrial method for producing artificial ammonia gas at industry level.
