question 6

identify the limiting reactant if 5 g of n2 is allowed to react with 5 g of h2 according to the chemical equation given below. determine the theoretical yield of the product nh3.

3 h2 + n2 à 2 nh3

limiting reactant is h2 ; theoretical yield = 6.07 g of nh3

limiting reactant is h2 ; theoretical yield = 28.33 g of nh3

limiting reactant is n2 ; theoretical yield = 6.07 g of nh3

limiting reactant is n2 ; theoretical yield = 28.33 g of nh3
