Question

For the following equilibrium
`N_(2)O_(4)(g)hArr 2NO_(2)(g)`
`K_(p)` is found to be equal to `K_(c)`. This is attained when `:`
A. `T=1K`
B. `T=12.18K`
C. `T=27.3K`
D. `=273K`

Answer 1

Correct Answer - B
`K_(p)=K_(c ) (RT)^(Deltan)`
`Delta n =2-1=1`
`:. K_(p)=K_(c)(RT)`
`K_(p)=K_(c)` when `RT =1`
`:. T=(1)/(R)`
`=(1)/(0.0821)=12.18K`
