Question

A student took 5 g of H₂ and 5 g of N₂ for the following reaction.

How many grams of NH₃ is expected to form?

3 H₂ + N₂ --> 2 NH₃

Answer 1

Answer #1

According to the balanced reaction,

3 mole H2 require 1 mole N2

3×2 = 6g H2 require 28 g N2

5 g H2 require 28×5/6 g N2

= 23.33 g N2

Since we have only 5 g N2 hence N2 is limiting reagent.

1 mole N2 give 2 mole NH3

28 g N2 give 2×17 = 34 g NH3

5 g N2 give 34×5/28 g NH3

= 6.07 g NH3
