On a given condition, the equilibrium concentration of `HI , H_(2)` and `I_(2)` are `0.80` , `0.10` and `0.10` mole/litre. The equilibrium constant for the reaction `H_(2) + I_(2) hArr 2HI` will be

A

64

B

12

C

8

D

`0.8`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_2+I_2hArr2HI,[HI]=0.80,[H_2]=0.10,[I_2]=0.10`
`K_c =([HI]^2)/([H_2][I_2])=(0.80xx 0.80)/(0.10 xx 0.10) =64`
