Question

For the reaction, $2N{O}_2\left(g\right)\rightleftharpoons 2NO\left(g\right)+O_2\left(g\right)$.
($K_c=1.8\times {10}^{-6}$ at ${184}^{o}C$
$(R=0.0831kJ/(mol.KJ\left)\right)$
when $K_p$ and $K_c$ are compared at ${184}^{o}C$ it is found that
(1) Whether $K_p$ is greater then, less then or equal to $K_c$ depends upon the total gas pressure
(2) $K_p=K_c$
(3) $K_p$ is less then $K_c$
(4) $K_p$ is greater then $K_c$

Answer 1

The answer will be matchable that is in the first case like$K_P>K_C$

The equations can be written as:

,

$K_P=K_C(RT{)}^{△n}$

$\Delta n=3-2=1$

$K_P=K_C(0.0831\times 457{)}^1$

$K_P>K_C$ and which is depends upon the total gas pressure.
