What is the relationship between the equilibrium constant Kp and Kc?
What is the relationship between the equilibrium constant Kp and Kc?
- Kp = Kc / (RT)∆n
- Kp = Kc (RT)∆n (correct)
- Kp = Kc + (RT)∆n
- Kp = Kc - (RT)∆n
What does a value of K >> 1 indicate about the reaction?
What does a value of K >> 1 indicate about the reaction?
- The reaction is irreversible
- The reaction is at equilibrium
- The reaction is product-favored (correct)
- The reaction is reactant-favored
Why does the equilibrium constant remain the same regardless of the initial concentrations of reactants and products?
Why does the equilibrium constant remain the same regardless of the initial concentrations of reactants and products?
- Because the reaction is at a fixed temperature
- Because the equilibrium constant is a ratio of concentrations (correct)
- Because the reaction is reversible
- Because the reaction rate is independent of concentration
