Change in volume of the system does not alter the number of moles in which of the following equilibria ?

Options

  1. AN ₂( ~g )+ O ₂( ~g ) 2 NO ( g )
  2. BPCl ₅( ~g ) PCl ₃( ~g )+ Cl ₂( ~g )
  3. CN ₂( ~g )+3 H ₂( ~g ) 2 NH ₃( ~g )
  4. DSO ₂ Cl ₂( ~g ) SO ₂( ~g )+ Cl ₂( ~g )

Correct answer

A. N ₂( ~g )+ O ₂( ~g ) 2 NO ( g )

Step-by-step solution

In this reaction the ratio of number of moles of reactants to products is same i.e. 2 : 2, hence change in volume will not alter the number of moles.
