If 5 moles of ammonia is produced in the reaction N2 + 3 H2 �¨ 2 NH3, the number of hydrogen moles consumed is ____?
7.5
To find the number of hydrogen moles consumed in the given reaction, we can use stoichiometry. The stoichiometry of the balanced equation tells us the ratio in which the reactants are consumed and the products are produced.
In the balanced equation N2 + 3 H2 → 2 NH3, we can see that for every 3 moles of hydrogen (H2), 2 moles of ammonia (NH3) are produced. Therefore, the ratio is 3:2.
Given that 5 moles of ammonia (NH3) are produced, we need to determine the moles of hydrogen (H2) required. We can set up a proportion using the ratio from the balanced equation:
3 moles H2 / 2 moles NH3 = x moles H2 / 5 moles NH3
Simplifying the proportion:
3/2 = x/5
Cross-multiplying:
2x = 15
Dividing by 2:
x = 7.5
Therefore, the number of hydrogen moles consumed in the reaction is 7.5 moles.
