Type: MCQ-numerical-Medium-Class 11
A vessel of one litre capacity containing 1 mole of SO₃ is heated till a state of equilibrium is attained. 2SO₃(g) ⇌ 2SO₂(g) + O₂(g). At equilibrium, 0.6 moles of SO₂ had formed. The value of equilibrium constant is
A
0.18
B
0.36
C
0.45
D
0.68
Correct Answer
Option D
Detailed Explanation
Equilibrium constant is given by K = [SO2]^2[O2] / [SO3]^2 = 0.675 = 0.68
