For the reaction :
`2NO_(2)(g)hArr 2NO(g)+O_(2)(g)`
`[K_(c )=1.8xx10^(-6)"at" 184^(@)C, R=0.0831 "kJ (mol, K)"]`
When `K_(p)` and `K_(c )` are compared at `184^(@)C`, it is found that :

Options

A. `K_(p)` is greater than `K_(c )`
B. `K_(p)` is less than `K_(c )`
C. `K_(p)=K_(c )`
D. whether `K_(p)` is greater than, less than or equal to `K_(c )` depend upon the total gas pressure.

Answer

A

Explanation

`K_(p)=K_(a)(RT)^(Delta n)`
`Delta n = 3-2=1`
`Delta n = 3-2=1`
`(K_(p))/(K_(C ))=(0.0831xx457). therefore K_(p)` is greater than `K_(c )`
