Question

The equilibrium constant for the reaction: \[\ce{N2_{(g)} + O2_{(g)} ⇌ 2NO_{(g)}}\] 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 catalyst of 2000 K is ______.

Options

• 40 × 10^–4 

• 4 × 10^–2 

• 4 × 10^–3 

• 4 × 10^–4 

Answer 1

The equilibrium constant for the reaction: \[\ce{N2_{(g)} + O2_{(g)} ⇌ 2NO_{(g)}}\] 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 catalyst of 2000 K is 4 × 10^–4.

Explanation:

The value of the equilibrium constant is unaffected by a catalyst.
