In which of the following equilibrium K c and K p are not equal?

Options

  1. A2 C ( s ) + O 2 ( g ) ⇌ 2 C O 2 ( g )
  2. B2 N O ( g ) ⇌ N 2 ( g ) + O 2 ( g )
  3. CS O 2 ( g ) + N O 2 ( g ) ⇌ S O 3 ( g ) + N O ( g )
  4. DH 2 ( g ) + I 2 ( g ) ⇌ 2 H I ( g )

Correct answer

A. 2 C ( s ) + O 2 ( g ) ⇌ 2 C O 2 ( g )

Step-by-step solution

As K p = K c is possible when n P = n R Here in case of 2 C ( s ) + O 2 ( g ) ⇌ 2 C O 2 ( g ) n P = 2 , n R = 1 So Δ n g = 2 - 1 = 1 K p = K c ( R T ) 1 K p > K c
