9 moles of "D" and 14 moles of E are allowed to react in a closed vessel according to given reactions. Calculate number of moles of B formed in the end of reaction if 4 moles of G are present in reaction vessel. (Percentage yield of reaction is mentioned in the reaction)
Step-1 3D + 4E \(\overset{80 \% }\rightarrow\)5C + A
Step-2 3C + 5G \(\overset{50 \%}\rightarrow\)6B + F
(a) 2.4
(b) 30
(c) 4.8
(d) 1

Correct answer: (a) 2.4
Explanation:
3D + 4E \(\overset{80 \% }\rightarrow\)5C + A
9 mole 14 mole \(\frac{5}{3}\)x 9 x 0.8 = 12 mole
3C + 5G \(\overset{50 \%}\rightarrow\)6B + F
Limiting Reagent is G
∴ Moles of B formed = \(\frac{6}{5}\) x 4 x 0.5 = 2.4
