Based on the equation of the reaction, nitrogen is the limiting reagent while hydrogen is the excess reagent.
<h3>What is the mole ratio of hydrogen to nitrogen in the formation of ammonia?</h3>
Hydrogen and nitrogen combines to form ammonia ina mole ratio of 3 : 1 as shown by the equation of the reaction below:
The number of moles of the reactants in 14g of Nitrogen gas and 8.0g of hydrogen is calculated as follows:
Molar mass of N_{2} = 14.0 g
Molar mass of H_{2} = 2.0 g
Moles of N_{2} = 14/14.0 = 1 mole
Moles of H_{2} = 8/2.0 = 4 moles
Based on the data above:
- The limiting reagent is nitrogen gas as it will be used up while hydrogen will be left over.
- The moles of nitrogen is 1 mole
- Hydrogen is the excess reagent and 1 mole will be left over
- 3 moles of hydrogen will react with 1 mole of the nitrogen gas
- mass of 3 moles of hydrogen is 3 × 2.0 g = 6.0g
Therefore, the limiting reagent is nitrogen while hydrogen is the excess reagent.
