In which of the following equilibria, K _ p and K _ c are NOT equal?

Options

  1. AH _ 2( ~g ) + I _ 2( ~g ) 2 HI _ ( g )
  2. BCO _ ( g ) + H ₂ O _ ( g ) CO _ 2( ~g ) + H _ 2( ~g )
  3. C2 BrCl _ ( g ) Br _ 2( ~g ) + Cl _ 2( ~g )
  4. DPCl _ 5( ~g ) PCl _ 3( ~g ) + Cl _ 2( ~g )

Correct answer

D. PCl _ 5( ~g ) PCl _ 3( ~g ) + Cl _ 2( ~g )

Step-by-step solution

aligned & K _ p = K _ c ( RT )^ n _ g & for K _ p K _ c & n _ g 0 & n _ g = n _ p - n _ r aligned (1) n _ g =2-2=0 (2) ng _ g =2-2=0 (3) ng _ g =2-2=0 (4) ng _ g =2-1=1
