In which of the following reaction K_p>K_c ?

Options

  1. APCl ₃+ Cl ₂ PCl ₅
  2. BH ₂+ I ₂ 2 HI
  3. C2 SO ₃ O ₂+2 SO ₂
  4. DN ₂+3 H ₂ 2 NH ₃ .

Correct answer

C. 2 SO ₃ O ₂+2 SO ₂

Step-by-step solution

K_p=K_c(R T)^ n n= change in number of moles If n= positive then K_p will be greater than K_c . array ll PCl ₃+ Cl ₂ PCl ₅, & n=1-2=-1 ; K_p K_c ~N ₂+3 H ₂ 2 NH ₃ ; & n=-2 ; K_p < K_c array
