NEET 2024 Chemistry Degree of Dissociation MCQ Question
Type: MCQ-numerical-Medium-Class 11
Consider the following reaction in a sealed vessel at equilibrium with concentrations of
N₂ = 3.0 × 10⁻³ M, O₂ = 4.2 × 10⁻³ M and NO = 2.8 × 10⁻³ M.
2NO(g) ⇌ N₂(g) + O₂(g)
If 0.1 mol L⁻¹ of NO(g) is taken in a closed vessel, what will be the degree of dissociation (α) of NO(g) at equilibrium?
A
0.8889
B
0.717
C
0.00889
D
0.0889
Correct Answer
Option B
Detailed Explanation
Using the equilibrium concentrations and the initial concentration of NO, the degree of dissociation can be calculated using the formula for equilibrium constant.
