Limiting reactant : Nâ‚‚

Excess reactant : Hâ‚‚

amount of NH₃ : 8 molecules

Further explanation

The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

[tex]\tt N_2+3H_2\rightarrow 2NH_3[/tex]

limiting reactant = smaller mol ratio

  • Nâ‚‚

[tex]\tt \dfrac{4}{1}=4[/tex]

  • Hâ‚‚

[tex]\tt \dfrac{15}{3}=5[/tex]

limiting reactant ⇒ N₂

The number of reacted Hâ‚‚ molecules :

[tex]\tt \dfrac{3}{1}\times 4=12[/tex]

The remaining Hâ‚‚ after the reaction :

[tex]\tt 15-12=3~molecules[/tex]

Amount of NH₃ :

[tex]\tt \dfrac{2}{1}\times 4=8~molecules[/tex]
