Solution
Correct Answer:
Both are in stoichiometric ratio
- Balanced Equation: N2+3H2→2NH3
- Moles present:
- Moles N2=28/28=1 mol.
- Moles H2=6/2=3 mol.
- Compare with stoichiometric ratio:
- The reaction requires N2:H2 in 1:3 ratio.
- The actual ratio present is 1:3.
- Result: Both reactants will be consumed completely; there is no limiting reagent.
