Question

Write the balanced chemical equation for the following reaction and identify the type of reaction :

Nitrogen gas is treated with hydrogen gas in the presence of a catalyst at 773 K to form ammonia gas.

Answer 1

$N_2+3H_2\stackrel{773K}{\to }{2NH}_3$

Nitrogen and hydrogen gases combine under specific conditions to form ammonia. This is an example of a combination reaction. It is also known as a synthesis reaction.

This reaction is used for industrial production of ammonia by the Haber process.
