Question

50 kg of N2 and 10 kg of H2 are mixed to produce NH3 calculate the ammonia formed identify the limiting reagent in the production of ammonia in this solution

Answer 1

3H2 + N2 = 2NH3

3mol H2 + 1molN2 = 2mol NH3

6gm H2 + 28gm N2 = 34gm NH3

6gm H2 react with 28gm N2

10000 gm H2 react with 46600gm N2

therefore,

H2 is the limiting reagent

6gm H2 produce 34gm NH3

10000gm H2 will produce 56600gm NH3
