Understanding the Equilibrium Constant
The equilibrium constant (K) is a crucial concept in chemical equilibrium, reflecting the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Why Option C is Correct
The correct answer is option 'C', which states that the equilibrium constant does not depend on the initial concentrations of reactants. Here's why:
- Equilibrium Position: The equilibrium constant is derived from the law of mass action, which expresses the relationship between the concentrations of reactants and products at equilibrium. It is defined as:
K = [Products]^coefficients / [Reactants]^coefficients
- Independence from Initial Concentrations: The value of K remains constant at a specific temperature regardless of the initial concentrations of reactants. This means that even if you start with different amounts of reactants, the equilibrium will shift to maintain the same value of K.
- Reaction Dynamics: As the reaction progresses, it approaches equilibrium where the rates of the forward and reverse reactions are equal. At this point, the concentrations stabilize, determining the equilibrium constant.
Misconceptions About Other Options
- Option A: Incorrect because K is independent of initial concentrations.
- Option B: Incorrect as K depends on all products and reactants, not just one product.
- Option D: Incorrect because K is characteristic of a particular reaction at a specific temperature.
Conclusion
In summary, the equilibrium constant is a fundamental property of a reaction that remains unaffected by the initial concentrations of reactants, reinforcing the unique nature of chemical equilibria.
