JEE Main Chemistry question

The equilibrium constant for the reaction N₂(g)+O₂(g)⇌2NO(g) is 4×10⁻⁴ at 2000 K. In presence of a catalyst the equilibrium is attained ten times faster. Therefore, the equilibrium constant in presence of the catalyst at 2000 K is:

• (A)40×10⁻⁴
• (B)4×10⁻⁴Correct
• (C)4×10⁻³
• (D)Difficult to compute without more data
