X, Y and Z react in the `1:1:1` stoichiometric ratio.
The concentration of X, Y and Z we are found to vary with time as shown in the figure below:

The value of the equilibrium constant `(K_(c))` for the equilibrium represented the in above sketch will be

A

`9/2`

B

`11/4`

C

`2/3`

D

`10/7`

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(,X(g),+,Y(s),hArr,Z(g)),("From graph",,,,,),(t=t_(Eq),6,,,,6),(("concentrated"),,,,,):}`
`:. K_(c)=([Z])/([X])=4/6=2/3`
