In which one of the following equilibria, pressure has no effect

Options

  1. APCl ₅ PCl ₃+ Cl ₂
  2. B2 NH ₃ N ₂+3 H ₂
  3. C2 SO ₂+ O ₂ 2 SO ₃
  4. DN ₂+ O ₂ 2 NO

Correct answer

D. N ₂+ O ₂ 2 NO

Step-by-step solution

When n_ g i.e. difference in gaseous moles of product and reactant is zero, then pressure has no effect and it is equilibrium point for reaction. aligned & N ₂(g)+ O ₂(g) 2 NO (g) & n_ g =2-(1+1)=0 aligned Pressure has no effect for this reaction.
