Question

Write the balanced chemical equations for the following reactions & identify the type of reaction in each case – 1. Nitrogen gas is treated with Hydrogen gas in the presence of a catalyst at 773K to form Ammonia gas. 2 Thermite reaction , Iron III Oxide reacts with Aluminium & gives molten Iron & Aluminium Oxide

Answer 1

Answer:

​

1) N2 + 3H2 + Catalyst/773 K ⇨ 2NH3

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.

2) 2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(l) + heat.

Iron(III) oxide (Fe2O3) reacts with aluminium(Al) to form aluminium oxide(Al2O3) and molten iron(Fe). This is a displacement reaction as aluminium displaces iron in iron(III)oxide to form aluminium oxide. Also it is a redox reaction as both oxidation of aluminium and reduction of iron is taking place.

Hope it helps you.
