SATHEE: Some Basic Concepts Of Chemistry Question 41

Some Basic Concepts Of Chemistry Question 41

Question: 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 $3 D + 4 E \overset{80 p e r c e n t}{\to} 5 C + A$ Step-2 $3 C + 5 G, \overset{50 p e r c e n t}{\to} 6 B + F$

Options:

A) 2.4

B) 30

C) 4.8

D) 1

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $3 D + 4 E \overset{80, p e r c e n t}{\to} 5 C + A$ 9 mole 14 mole $\frac{5}{3} \times 9 \times 0.8 = 12$ mole $\underset{12, m o l e}{3 C}, + \underset{4 m o l e}{5 G}, \overset{50, p e r c e n t}{\to} 6 B + F$ Limiting Reagent is G
$∴$ Moles of B formed $= \frac{6}{5} \times 4 \times 0.5 = 2.4$
