what will volume of ammonia gas when 100cm^3of nitrogen reacts with 150cm^3of hydrogen?which is the limiting reactant?

Answer 1

N2 + 3H2 ==> 2NH3
100 cc....150 cc........xxx
Determine the limiting reagent.
Using the coefficients like this:
100 cc N2 will produce 200 cc NH3 and
150 cc H2 will produce 150 x 2/3 = 100 cc NH3; therefore,H2 is the limiting reagent (LR) and N2 is the excess reagent (ER). 100 cc of NH3 gas will be produced.
