The equilibrium constant 'K' of a chemical reaction depends on_________________?
Correct answer: C. Temperature only
- A. Temperature and pressure
- B. Pressure only
- C. Temperature only
- D. Ratio of reactants
Explanation
For a specified reaction, the equilibrium constant changes with temperature through the standard Gibbs-energy relation. Pressure may alter equilibrium composition, especially for gas reactions, but it does not directly change the value of K at fixed temperature.
