`1` mol of `H_(2), 2` mol of `I_(2)` and `3` mol of HI were taken in a `1-L` flask. If the value of `K_(c)` for the equation `H_(2)(g)+I_(2)(g) hArr 2HI(g)` is `50` at `440^(@)C`, what will be the concentration of each specie at equilibrium?

A

0.3

B

1.3

C

4.4

D

2.7

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)+I_(2) Leftrightarrow 2HI`
Intial : 1 mole 2 mole 3 moles
At equilibrium (1-x) (2-x) (3+2x)
`K_(C)=([HI]^(2))/([H_(2)] [I_(2)])`
