Question

Which statement about the manufacture of ammonia by the Haber's process is correct?

• A. The reactants and product are solids.
• B. The reactants and product are gases.
• C. The reactants are in different physical states.
• D. The reactants and product are liquids.

Answer 1

The correct option is B The reactants and product are gases.

In the Haber's process, nitrogen and hydrogen are combined at high temperature and pressure in the presence of spongy iron as a catalyst.

$N_2\left(g\right)+3H_2\left(g\right)⟶2N{H}_3\left(g\right)$

Here, the reactants and product are gases.
