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)xx R^(-1)`

Answer

D

Explanation

`K_p=K_c(RT)^(Delta n), Deltan=4-3=1`
`0.05K_c=Rxx1000`
`K_c=5xx10^(-5)xxR^(-1)`
`K_c=(5xx10^(-5))/(R)`
