One mole of A_((g)) is heated to 300^(@) Cin a closed one litre vessel

1.	One mole of A_((g)) is heated to 300^(@) Cin a closed one litre vessel till the following equilibrium is reached. A_((g)) hArr B_((g) .The equilibrium constant of the reaction at 300^(@) C is 4. What is the conc. of B ("in. mole. lit"^(-1))at equilibrium ?
Answer» 0.2 0.6 0.8 0.1 Solution : `K_(C)=(x)/(1-x)=4 implies 4-4x=x` 5x-4, x=0.8 M=[B]
