Which of the following factors does not affect the value of the equilibrium constant for a chemical reaction?
- A.Temperature
- B.Initial concentration of reactants
- C.Presence of a catalyst
- D.Both Band C
Show correct answer & step-by-step solution
Correct answer: D — Both Band C
Solution
- The equilibrium constant is a function of temperature only.
- Changing the initial concentration of reactants shifts the equilibrium position but does not change the value of .
- A catalyst increases the rate of both forward and backward reactions equally, leaving unchanged.
- Therefore, both initial concentration and catalyst do not affect .
- Hence the answer is (D).
