At 1000 K, the value of `K_(p)` for the reaction: `A(g) + 2B(g)hArr3C(g) + D(g)` is `0.05` atmosphere. The value of `K_(c)` in terms of R would be:

Options

A. 20000 R
B. 0.02 R
C. `5xx10^(-5)R`
D. (5xx10^(-5))/(R )`

Answer

D

Explanation

`K_(p)=K_(c)(RT)^(Deltan)=K_(c) (RT)`
`[ :' Deltan=4-3=1]`
or `K_(c)=(K_(p))/(RT)=(0.05)/(R xx 1000)=(5xx10^(-5))/(R)`
