Kp value for 2SO(2(g)) O(2(g)) hArr 2SO...

Kp value for `2SO_(2(g)) O_(2(g)) hArr 2SO_(3(g)) ` is 5.0 `atm^(-1)`. What is the cquilibrium partial pressure of `O_(2)` if the equilibrium pressures of `SO_(2) and SO_(3)` are equal ?

A

0.2

B

0.3

C

0.4

D

0.1 atm

Text Solution

Verified by Experts

The correct Answer is:
A
`2SO_(2(g))+O_(2(g)) harr 2SO_(3(g))`
`K_(P)=(P_(SO_(3))^(2))/(P_(SO_(2))^(2) xx P_(O_(2)))=(1)/(P_(O_(2)))` (`:. P_(SO_(3))=P_(SO_(2))`)
`PO_(2)=(1)/(K_(P))=(1)/(5)=0.2` atm
