Question

12g of hydrogen react with 28g of nitrogen to form 17g of NH3. Here the limiting reactant and percentage yield are?

Answer 1

Answer:

The Limiting reactant is Nitrogen.

Explanation:

3H2 +N2----->2NH3

From the given stiochiometric equation it can be seen:

6g of H2------>34g of NH3

then. 12g of H2 -------> 34×12÷6

=68g of NH3

28g of N2=34g of NH3

• The Limiting reactant is Nitrogen

Percentage yield:

Here the actual yield =17g

and theoretical yield =34g

%yield= A.Y/T.Y ×100

=17/34 ×100

=50%
