AIIMS2018ChemistryChemical Equilibrium
A vessel of one litre capacity containing 1 mole of SO ₃ is heated till a state of equilibrium is attained. 2 SO _ 3(g) 2 SO _ 2(g) + O _ 2(g) At equilibrium, 0.6 moles of SO ₂ had formed. The value of equilibrium constant is
Options
- A0.18
- B0.36
- C0.45
- D0.68
Correct answer
D. 0.68
Step-by-step solution
2 SO _ 3(g) 2 SO _ 2(g) + O _ 2(g) array lcl Inital conc. 1.0 mole & 0.0 mole & 0.0 mole Equilibrium 0.4 mole & 0.6 mole & 0.3 mole Equilibrium constant is given by K= [ SO ₂ ]^2 [ O ₂ ] [ SO ₃ ]^2 = (0.6)^2(0.3) (0.4)^2 =0.675 0.68 array
