Question

if 30 cubic Decimeter of each reactant react together then the volume of the mixture at the end in Ammonia reaction is​

Answer 1

Answer:

20 cubic decimeter

Explanation:

Haber's Process is used to manufacture ammonia. For ease, consider uniform temperature and pressure

N2 + 3H2 --> 2 NH3

Given, both reactants = 30 decimeter

According to reaction,

1 cubic decimeter N2 needs = 3 cubic decimeter H2

30 cubic decimeter N2 needs = 30x2 = 60 cubic decimeterH2

But we have only 30 cubic decimeter H2. This means H2 is limiting reagent and H2 decides how much NH3 will form.

3 cubic decimeter H2 forms  = 2 cubic decimeter NH3

1 cubic decimeter H2 forms  = 2/3 cubic decimeter NH3

30 cubic decimeter H2 forms  = 2/3 x 30 = 20  cubic decimeter NH3

Hence, 20 cubic decimeter is formed
