Question

In Haber’s process, the volume of ammonia relative to the volume of reactants at STP is.
A) One fourth.
B) One half.
C) Same.
D) Three fourth.

Answer 1

We know the Haber process for the synthesis of ammonia is predicated on the reaction of nitrogen and hydrogen. The reaction is given below. Notably, during this process, the reaction is a chemical reaction one where there's a release of energy. We can write the chemical equation for this above reaction as follows,
${N_2}\left( g \right) + 3{H_2}\left( g \right) \to 2N{H_3}\left( g \right)$

Complete step by step answer:
The proportions of nitrogen and hydrogen: The mixture of nitrogen and hydrogen going into the reactor is within the ratio of 1 volume of nitrogen to three volumes of hydrogen. Avogadro's law says that equal volumes of gases at an equivalent temperature and pressure contain equal numbers of molecules. Meaning that the gases are entered into the reactor within the ratio of 1 molecule of nitrogen to three of hydrogen. That’s the proportion demanded by the equation.
${N_2}\left( g \right) + 3{H_2}\left( g \right) \to 2N{H_3}\left( g \right)$
The total volume of reactants at STP is $4x$ .
The volume of ammonia is $2x$ .
Thus, the volume of ammonia is equal to${\text{ }}1/2\left( {{\text{Volume of reactant}}} \right)$.

So, the correct answer is Option B.

Note:
Now we discuss about the uses of ammonia as,
Uses of Ammonia:
Production of ammonia is vital because it is one among the most components in making fertilizers.
Ammonia produced is employed in making nitro-based explosives including TNT, RDX, etc.
It's utilized in manufacturing certain sorts of drugs like sulfonamide, antimalarials, and vitamins like thiamine and nicotinamide.
It's also utilized in large-scale refrigeration plants, air-conditioning units in Buildings, etc.
Ammonia is employed in various cleaning products and acts as an efficient cleaning agent.
