Question

How many grams of H2 must react, if the reaction needs to produced 63.5g of NH3?

Answer 1

◼$\bold{When \: hydrogen \: and nitrogen \: reacts \:to }$$\bold{form \: ammonia \: they \: do \: so \: in \: ratio \: 1:3}$

$\boxed{N_2 +3H_2 \xrightarrow{450 - 500 \: degrees \: Fe} 2NH_3 + \Delta}$

◼The following reaction does happens in preparation of ammonia by Haber's process.

✳The reaction is exothermic as 22 ,400 cals of heat is produced.

✳Low temperature and high pressure is makntaubed during reaction.

◼By the equation we can convey that

▶2 volumes of ammonia is formed when 3 volumes of hydrogen reacts with nitrogen

▶1 volume of ammonia will be formed when $\dfrac{3}{2}$of hydrogen will react with nitrogen.

▶63.5 g of ammonia will be formed when =$\dfrac{3 \times 63.5}{2}$ will react with nitrogen.

So,

=$\dfrac{3 \times 63.5}{2}$

$\large \boxed{95.25 \: g}$
