NEET Chemistry Chemical Equilibrium MCQ Question

Type: MCQ-numerical-Hard-Class 11

For the reaction 2N₂(g) + O₂(g) ⇌ 2N₂O(g), if the initial concentrations in a 10 L vessel are 0.482 mol N₂ and 0.933 mol O₂, and the equilibrium constant Kₑ = 2.0 × 10⁻³⁷, what is the equilibrium concentration of N₂O?

A

2.0 × 10⁻³⁷ M

B

0.0 M

C

4.82 × 10⁻² M

D

9.33 × 10⁻² M

Correct Answer

Option B

Detailed Explanation

Given the extremely low value of Kₑ, the reaction does not proceed significantly in the forward direction, resulting in negligible formation of N₂O.
