The equilibrium constant for the reaction
\( \mathrm{N}_{2}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 N O(g) \) is \( 4 \times 10^{-4} \) at \( 2000 \mathrm{~K} \). In presence of a catalyst the equilibrium is
attained ten times faster. Therefore the equilibrium constant in presence of catalyst of \( 2000 \mathrm{~K} \)
is
- A \( 4 \times 10^{-3} \)
- B \( 4 \times 10^{-2} \)
- C \( 4 \times 10^{-3} \)
- D \( 4 \times 10^{-4} \)
Answer & Solution
Correct Answer
(D) \( 4 \times 10^{-4} \)
Step-by-step Solution
Detailed explanation
Since, equilibrium constants \( (K C) \) is not affected by addition of catalyst. Therefore, the equilibrium constant value
remains \( 4 \times 10^{-4} \).
remains \( 4 \times 10^{-4} \).
