The equilibrium constant for the given reaction is 100 . N ₂(g)+2 O ₂(g) 2 NO ₂(g) What is the equilibrium constant for the reaction given below? NO ₂(g) 1 2 ~N ₂(g)+ O ₂(g)
Options
- A10
- B1
- C0.1
- D0.01
Correct answer
C. 0.1
Step-by-step solution
gathered N ₂+2 O ₂ 2 NO ₂ K₁= [ NO ₂ ]^2 [ ~N ₂ ] [ O ₂ ]^2 gathered or 100= [ NO ₂ ]^2 [ ~N ₂ ] [ O ₂ ]^2 (i) Again, aligned [ NO ₂ ] & 1 2 ~N ₂+ O ₂ K₂ & = [ N ₂ ]^ 1 / 2 [ O ₂ ] [ NO ₂ ] aligned Eqs. (i) (ii), we get gathered 100 K₂^2=1 or K₂^2= 1 100 or K₂= 1 10 =0.1 gathered
