Question

The reaction N₂ + 3H₂ → 2NH₃ is used to produce ammonia. When 450 g of hydrogen was reacted with nitrogen, 1575 g of ammonia were produced. The percentage yield of reaction is closest to

(a) 61.8

(b) 72.4

(c) 51.8

(d) 89.1

Answer 1

Answer is : (a) 61.8

N₂ + 3H₂ → 2NH₃

6 g of hydrogen produces 34 g of NH₃

∴ 450 g of hydrogen produces

= 34/6 x 450 = 2550 g of NH₃

Actual ammonia produced in the solution
