XY(2) dissociates XY(2)(g) hArr XY(g)+Y(...

`XY_(2)` dissociates `XY_(2)(g) hArr XY(g)+Y(g)`. When the initial pressure of `XY_(2)` is `600` mm Hg, the total equilibrium pressure is `800` mm Hg. Calculate K for the reaction Assuming that the volume of the system remains unchanged.

A

`50`

B

`100`

C

`200`

D

`400`

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(XY_(2)(g),hArr,XY(g),+,Y(g)),(600-x,,x,,x):}`
`:. 600+x =800`
`x=200`
