Equilibrium Question 577
Question: 3.2 moles of hydrogen iodide were heated in a scaled bulb at 444°C till the equilibrium was reached. The degree of dissociation of HI at this temperature was found to be 22%. The number of moles of hydrogen iodide present at equilibrium are [MH CET 2001]
Options:
A) 1.87
B) 2.496
C) 4.00
D) 2.00
Show Answer
Answer:
Correct Answer: B
Solution:
Given $ x=\frac{22}{100} $ and $ a=3.2 $
HI at equilibrium =3.2[$ 1-\frac{22}{100} $]=2.496
