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) ifthe equilibrium pressures of SO_(2) and SO_(3) are equal ?

Answer»

<P>0.2
0.3
0.4
0.1 atm

Solution :`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
