Question

1.05 g H2 is allowed to react with 10.4 g N2 , producing 2.07 g NH3 .

What is the theoretical yield in grams for this reaction under the given conditions?

Express your answer to three significant figures and include the appropriate units.

Answer 1

The reaction between the H₂ and N₂ is simple addition reaction to form NH₃. Like,

N₂ + 3H₂ = 2NH₃

_{Therotical yield of any reaction is calculated on the basis of wt of reactants involved in reaction to get the product.}

In the given reaction, We use wt of reactant taken to calculate Theorotical yield,

Therotical yield = Wt of N₂ + Wt of H₂

(As the reaction is simple addition just add the wt of reactant taken; this formula is not used for other type of reaction)

Hence,

Therotical yeild = 10.4 g + 1.05 g

= 11.45 g

So, The Theorotical yield of given reaction is 11.45 g.
