The equilibrium constant for the reaction N 2 ( g ) + O 2 ( g ) ⇌ 2 N O ( g ) is 4 × 1 0 - 4 at 2000 K. In presence of a catalyst, the equilibrium is attained ten times faster. Therefore, the equilibrium constant, in presence of the catalys

Question

The equilibrium constant for the reaction N 2 ( g ) + O 2 ( g ) ⇌ 2 N O ( g ) is 4 × 1 0 - 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

Quantrex Academy · Accepted Answer

Correct answer: B. 4 × 1 0 - 4

The presence of catalyst does not affect the magnitude of equilibrium constant. In presence of a catalyst the equilibrium is attained sooner.

The equilibrium constant for the reaction N 2 ( g ) + O 2 ( g ) ⇌ 2 N O ( g ) is 4 × 1 0 - 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
