Answer: equal to Kc.
- A greater than Kc
- B less than Kc
- C equal to Kc
- D equal to zero
Correct answer: C. equal to Kc
Explanation: When Δn = 0, (RT)^Δn = 1, so Kp = Kc.
As the reaction proceeds, reactant concentration falls and product concentration rises until both level off at equilibrium.
Concept context
When forward and reverse reaction rates are equal, equilibrium is reached. Learn about Kc, Kp, Le Chatelier's principle, and acid-base equilibria, including pH, buffer solutions, and solubility product.
