Question

the reaction,N2+3H2->NH3 is used to produce ammonia.When 450g of hydrogen is reacted with nitrogen, 1575g of ammonia were produced. What is the percentage yield of the reaction?

Answer 1

Answer:

61.76%

Explanation:

balanced chemical reaction is

N2+3H2-->2NH3

molar mass of H2= 2g

molar mass of NH3= 34g

here 3 moles of H2 i.e. 3*2=6g of H2 produce 34g of N2(i.e. 1mole)

450g of H2 should produce= 34*450/6= 2550g ofNH3

actual yield=1575g

%age yield= 100*1575/2550= 61.76%
