Question

Eight moles of a gas AB 3 ​ attain equilibrium in a closed container of volume 1 dm 3 as : 2 AB 3 ​ ⇌ A 2 ​ ( g ) + 3 B 2 ​ ( g ) . If at equilibrium 2 moles of A 2 ​ are present then equilibrium constant is

TestHub · Accepted Answer

2 A B 3 ​ ⇌ A 2 ​ ( g ) + 3 B 2 ​ ( g ) : Initial moles: 8 0 0 Final moles: ( 8 − 4 ) 2 6 K c ​ = [ A B 3 ​ ] 2 [ A 2 ​ ] [ B 2 ​ ] 3 ​ = ( 4 ) 2 ( 2 ) ( 6 ) 3 ​ = 16 2 × 216 ​ = 16 432 ​ = 27 ( m o l / L ) 2
