The equilibrium constant for the reactio...

The equilibrium constant for the reaction `w+x hArr y+z` is `9`. If one mole of each of w and x are mixed and there is no change in volume, the number of moles of y for formed is

A

`0.10`

B

`0.50`

C

`0.75`

D

`0.54`

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(,W,+,X,hArr,Y,+,Z","),("Initial",1,,1,,0,,0),("At eq.",1-x,,1-x,,x,,x):}`
`K=9=x^(2)/((1-x)^(2))`
`:. x=0.75`
moles of `y=x=0.75`
