Question

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

TestHub · Accepted Answer

2 SO 3 ( g ) ​ ⇌ 2 SO 2 ( g ) ​ + O 2 ( g ) ​ Inital conc. 1.0 mole Equilibrium 0.4 mole ⇒ Equilibrium constant is given by K = [ SO 3 ​ ] 2 [ SO 2 ​ ] 2 [ O 2 ​ ] ​ = ( 0.4 ) 2 ( 0.6 ) 2 ( 0.3 ) ​ = 0.675 ≈ 0.68 ​ 0.0 mole 0.6 mole 0.0 mole 0.3 mole
