KCET2023ChemistryChemical Equilibrium
At 500 ~K , for a reversible reaction A₂(g)+B₂(g) 2 A B(g) in a closed container, K_C=2 10⁻⁵ . In the presence of catalyst, the equilibrium is attaining 10 times faster. The equilibrium constant K_C in the presence of catalyst at the same temperature is
Options
- A2 10⁻⁴
- B2 10⁻⁶
- C2 10⁻¹⁰
- D2 10⁻⁵
Correct answer
D. 2 10⁻⁵
Step-by-step solution
The value of the K_C remains same as catalyst does not affects the K_C . Only temperature can alter the value of the K_C of a given reaction. Thus, the equilibrium constant K_C in the presence of catalyst at the same temperature is 2 10⁻⁵ .
