One mole of A((g)) is heated to 300^(@) ...

One mole of `A_((g))` is heated to `300^(@)` C in 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 ?

A

0.2

B

0.6

C

0.8

D

0.1

Text Solution

Verified by Experts

The correct Answer is:
C

`K_(c)=(x)/(1-x)=4 implies 4-4x=x`
5x-4, x=0.8 M=[B]
