JEE Main 2022 — Chemical Equilibrium Question with Solution
From: JEE Main 2022 (Online) 27th June Morning Shift
Question
2NOCl(g) 2NO(g) + Cl2(g)
In an experiment, 2.0 moles of NOCl was placed in a one-litre flask and the concentration of NO after equilibrium established, was found to be 0.4 mol/L. The equilibrium constant at 30C is ______________ 104.

Step-by-step explanation
Given that at equilibrium, concentration of NO = 0.4 mol/L
2x = 0.4
x = 0.2
Concentration of NOCl at equilibrium,
[NOCl]eq = 2 2 0.2 = 1.6
and [NO]eq = 0.4
and [Cl2]eq = 0.2
