Question

For the reaction, `2NO_(2(g))hArr2NO_((g)) + O_(2(g)) K_(c) = 1.0xx10^(-6)` at `184^(@)C` and `R = 0.083 jK^(-1)"mol"^(-1)`. When `K_(p)` and `K_(c)` are compared at `184^(@)C`, it is found that:
A. `K_(p) gt K_(c)`
B. `K_(p) lt K_(c)`
C. `K_(p) = K_(c)`
D. `K_(p)xxK_(c)` depends upon pressure of gases

Answer 1

Correct Answer - A
`K_(p) = K_(c)(RT)^(Delta n)`
`.: Delta n = 3 - 2 = + ve`
`:. K_(p) gt K_(c)`
