The equilibrium constant for the reaction `N_2(g) + O_2(g) ⇌ 2NO(g) is 4×10^–4` at 200. In the presence of a catalyst, the equilibrium is attained 10 times faster. Therefore, the equilibrium constant in the presence of the catalyst at 200 K is :–
| A. |
`4×10^(–3)` |
| B. |
`4×10^(–4)` |
 |
| C. |
`4×10^(–5)` |
| D. |
None |
Equilibrium constant of a reaction remains unchanged when the same reaction remains unchanged. When the same reaction is carried out in the presence of a catalyst because the catalyst will catalyse both the forward and backward reaction equally
