n C =(26 g /12 g / mol )=2.16 n O 2=(20 g /32 g / mol )=0.625 O 2 will be a limiting reagent in reaction (i) n N 2=(60 g /28 g / mol )=2.14 n H 2=40 According to balanced equation, 1 mol of N 2 requires 3 mole of H 2 2.14 mol of N 2 require 6.42 mol of H 2 N 2 will be a limiting reagent in reaction (ii) n P 4=(100 g /4 × 31)=0.86 ; n O 2=6.25 According to balanced equation 1 mol of P 4 require 3 mol of O 2 0.86 mol of P 4 require 2.58 mol of O 2 So, P 4 is a limiting reagent in reaction (iii)
