Question

In Haber's process, the volume of ammonia relative to the total volume of reactants at STP is:

• A. one fourth
• B. one half
• C. same
• D. three fourth

Answer 1

Answer: (B)

one half

This reaction occurs in Haber's process-

$N_2$ + $3H_2$ $\to$ $2N{H}_3$

The total volume of reactants at STP is 4x

The volume of ammonia is 2x.

Hence, Volume of ammonia = $\frac{1}{2}$(Volume of reactant)
