The values of `K_(p)//K_(c)` for the following reactions at 300 K are, respectively :
(At 300 K, RT = 24.62 d`m^(3)` atm `mol^(-1)`)
`N_(2)(g)+O_(2)(g)hArr 2 NO(g)`
`N_(2)O_(4)(g)hArr2 NO_(2)(g)`

A

`1,4.1 xx 10 ^(-2) dm^(-3) atm^(-1) mol, 606 dm^(6) atm^(2) mol^(-2)`

B

`1, 24 .62 dm^(3) atm ^(-1) mol ^(-1) , 1.65 xx 10^(-3) dm ^(-6) atm ^(2) mol ^(-2)`

C

`24.62 dm^(3) atm mol ^(-1) , 606.0 dm^(6) atm^(2) mol^(-2), 1.65 xx 10 ^(-3) dm^(-6) atm^(-2) mol^(2)`

D

`1.24.64 dm^(2) atm mol^(-1) , 606.0 dm^(6) atm^(2) mol^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(P) // K_(C) = (RT)^(Delta n_(g))`
`{:((1),Delta n_(g) = 0 ,,,(K_(P))/(K_(C))=1),((2),Delta n_(g)=2-1=1,,,(K_(P))/(K_(C))=(RT)^(1)= (24.62)^(1)),((3),Delta n_(g) = 2 - 4 = - 2,,,(K_(P))/(K_(C))=(RT)^(-2)= (24.62)^(-2)):}`
`= 1.65 xx 10^(-3)`
