Question

The equilibrium constant for the reaction : $N_2\left(g\right)+O_2\left(g\right)\rightleftharpoons 2NO\left(g\right)$ at 2000 K is $4\times {10}^4$. in presence of a catalyst, the equilibrium is established ten times faster at the same temperature. What is the value of equilibrium constant in presence of catalyst?

• A. $4\times {10}^{-4}$
• B. $40\times {10}^{-4}$
• C. $4\times {10}^4$
• D. None of the above

Answer 1

The correct option is C $4\times {10}^4$

In the presence of the catalyst equilibrium is established faster but the equilibrium conditions and $K_C$ will not change.
