K_(p) for the reaction H_(2)(g)+(1)/(2)O_(2)(g)hArrH_(2)O(l) is 8.0 "bar"^(-3//2) at T kelvin temperature. If vapour pressure of H_(2)O is 2.0 bar at same temperature then K_(P)^(0) for the reaction 2H_(2)(g)+O_(2)(g)hArr2H_(2)O(g) is

Answer»

`8.0`
64
16
256

Solution :`H_(2)(g)+(1)/(2)O_(2)(g)hArrH_(2)O(L)`
`k_(p_(i))=8"BAR"^(-3//2)`
`H_(2)O(l)hArrH_(2)O(g)`
`K_(p_(2))=V.P.` of `H_(2)O=2` bar
`H_(2)(g)+(1)/(2)O_(2)(g)hArrH_(2)O(g)`
`K_(P)=K_(p_(i))xxk_(p_(2))`
`2H_(2)(g)+O_(2)(g)hArr2H_(2)O(g)`
`K_(p)=(k_(p_(1))xxK_(p_(2))^(2)`
`(8xx2)^(2)"bar"^(-1)=256 "bar"^(1)`
`k_(p)^(0)=256`
