Question

aa Sapling Learning Nitrogen and hydrogen combine at high temperature, in the presence of a catalyst, to produce ammonia. Assume 4 molecules of nitrogen and 9 molecules of hydrogen are present. Number After complete reactionare produced?1m8 0.778 How many molecules of H2 remain?028 Number How many molecules of N2 remain?o What is the limiting reactant?

Explanation / Answer

Answer

Molecules of ammonia produced = 6

Molecules of Hydrogen remain = 0

Molecules of Nitrogen remain = 1

Limiting reagent is Hydrogen

Explanation

N2(g) + 3H2(g) -------> 2NH3(g)

stoichimetrically, 3 mole of H2 react with 1 mole of N2 to produce 2 mole of NH3

No of molecule of H2 = 9

No of molecule of N2 = 4

4 Molecule of N2 require 12 molecule of H2

But available molecule of H2 is 9

So, Hydrogen is limiting

9 molecule of Hydrogen react with 3 molecule of N2

6 molecule of NH3 will produce

1 molecule of N2 will remain
